2021 年 5 月,萊克斯·弗裡德曼坐在一臺跑著 Ubuntu 20.04 的機器旁邊,頭上扣著一頂形似腳踏車頭盔的裝置。對面的布萊恩·約翰遜說,我來給你講幾個笑話,你的任務是別笑。萊克斯是俄羅斯人,布萊恩補了一句,這一項你該有優勢,別給祖國丟臉。

第一個笑話問的是土豆腦子裡在想什麼。答案是"土豆的想法"。萊克斯一秒破功,笑到懷疑人生。

那頂頭盔叫 Kernel Flow,一臺用光譜學原理工作的腦成像裝置。它正在讀取他整個大腦皮層的活動。

不貼電極、不進核磁共振艙、不用開顱,戴在頭上就行。布萊恩說,神經元以電化學方式放電,帶動區域性血氧水平變化,我們測的就是這個。整體有一千多個通道同時在取樣。

萊克斯的反應很有意思。他說,我感覺自己被聽見了。

被聽見的物件是那臺機器,不是對面那個人。就像你有個好朋友,他真的在聽你說話,不急著輪到自己開口。萊克斯說,這種感覺沒法完全用語言描述,但那一刻,來自他頭腦的資訊的完整豐富度,被一臺機器記錄了下來。

"我的狀態、我的專注程度,所有這些,被聽見了。"(萊克斯·弗裡德曼)

這場對話的後半段,兩個人從這個"被聽見"的感覺出發,一路聊到了腦機介面的技術路線、意識的工程化、隱私的規則重建、加密貨幣、一天只吃一頓的飲食實驗,還有乞力馬扎羅山上的一場死鬥。

光子在顱骨裡散射,一千多個通道同時取樣

Kernel Flow 的原理並不神秘。手腕上的可穿戴裝置用光測血氧,Kernel 用的是鐳射雷達級別的光學手段,去成像大腦的功能活動。

硬體層面,頭盔裡有 52 個模組,每個模組配一個鐳射器和六個感測器。感測器在約 100 皮秒的時間尺度上發射光子,光子進入大腦,散射、被吸收,一小部分再跑出來,被感測器接住。把返回的光子數做重建,就得到大腦血氧的變化圖。

機械設計上,這個版本要能容納大多數成年人的頭。萊克斯有點擔心自己的頭太大,結果戴上去意外地合適。他本來以為"測量大腦活動"的裝置應該很不舒服,實際上這個可以帶回家。布萊恩順手補了一刀:大多數人習慣了 fMRI 那種 120 分貝噪音加幽閉空間的體驗,或者 EEG 那種黏糊糊的電極,或者乾脆開顱。能戴在頭上、在你自選的環境裡記錄腦活動,這件事本身就是一種自由。

萊克斯提到另一個感受:旁邊那臺 Ubuntu 機器在實時採集他的資料,這讓他覺得自己"更重要了"。他說得很玄,意思卻很清楚,一臺他熟悉的開源系統,正在用一種他以前無法使用的方式和他交流。

從控制到測量:腦機介面真正該被理解的方式

布萊恩說,大眾對腦機介面的直覺,基本停留在"控制"這個框架裡:移動游標、打字、換頻道、切歌。這套直覺來自科幻電影,根深蒂固。

他給出的替代框架是"測量系統"。

一旦某個東西有了數字,圍繞這些數字能長出無窮無盡的可能性。體溫、心率、步數、血糖,每一項被量化之後,都長出了產品、臨床路徑和行為改變方案。大腦活動目前還沒有走到這一步。

萊克斯順著往下推。他自己是搞機器學習的,對"把身體和心智的資訊轉成資料"這件事本來就興奮。手環那點資料太粗糙了,解析度低到沒多大意思。從大腦裡以高頻寬、乾淨的方式拿到資料,屬於完全不同的量級。

他舉了個例子:安德魯·胡伯曼是神經科學家,他自己是資料科學的人,兩人正在合作寫一篇關於眼球運動和大腦測量的論文。這種"神經科學家加機器學習研究者"的組合,正在把腦資料變成研究人類行為的嚴肅工具。不只是個人級的 Fitbit 式自我量化,還包括大規模人群研究。

布萊恩說,這正是 Kernel 的核心賭注。人類已經把周圍的世界量化得相當好了,從遙遠的恆星到卡路里、步數、基因組,幾乎什麼都能測。唯一沒被系統量化的,是我們自己的頭腦。

人類唯一沒被工程化的東西

布萊恩有一套很完整的論述。

他說,人類思想、人類認知,很可能是社會里最大的單一原材料輸入。我們每時每刻和自己的對話、和他人的對話,體量驚人,卻從來沒有被測量過。

他舉了個生活化的對比:你去商店買一臺電器,不用掏出捲尺量它能不能穿過你家門框,因為電器的製造和建築行業早就有了統一的工程標準。人人認可,人人遵守。

認知沒有這種標準。

"認知還沒有作為一種正式的工程學科進入社會,去和別的東西搭接,包括我們消費新聞的方式、我們的關係、政治、經濟、教育。"(布萊恩·約翰遜)

他說,Kernel 能做的最大貢獻,就是把認知引入正式工程化的軌道。

萊克斯追問了一個關鍵點:從腦資料到"認知",中間是不是有個巨大的跳躍?我們連認知的大部分構成都還沒搞懂。

布萊恩承認這是 Kernel 最難的部分,並且講了一段融資史。他跟投資人聊天,對方的第一反應永遠是:殺手級應用是什麼?他理解這套邏輯,投資人要的是風險對沖:產品解決了嗎?有客戶群嗎?有人願意付錢嗎?和競品比怎麼樣?

而腦機介面這門生意,剛開始的時候,連"能造出技術"的路徑都不存在。所以布萊恩自己掏了 5300 萬美元,把公司從零撐起來。等到要正式融資,他見了 228 個投資人。

只有一個說 yes。

所以 Kernel 內部的打法更接近德雷克方程(Drake equation)。德雷克方程是用來估算銀河系裡可能存在的文明數量的,變數多、不確定性大、結果只是個機率區間。布萊恩說,他們就是這麼看待商業化路徑的:先把技術做到某個閾值,然後把發現價值的過程交給一個更大的系統。

心臟病醫生不會憑感覺給你開他汀

聊到致幻劑時,布萊恩打了一個很精準的比方。

假設我們關心的是你的心臟健康。你坐下來閉眼想了想,說,感覺還行。然後你去了心內科,醫生說,萊克斯,跟我說說你的感覺。你會覺得這醫生是不是瘋了。你要的是心電圖、血脂、動脈斑塊、膽固醇,五到十項檢查,一份量化報告,然後基於這份報告開運動處方,可能再加個他汀。

而今天的精神健康,就是那個"憑感覺開藥"的版本。

"你會覺得心內科醫生瘋了。但這就是我們對待心理健康的方式。說實話,這挺荒謬的。"(布萊恩·約翰遜)

放到致幻劑上,邏輯是一樣的:先測基線狀態,再測服藥期間、服藥之後,然後做縱向追蹤。有了量化,你才能開始問真正有意義的問題:哪種分子、什麼劑量、什麼頻率、什麼環境、搭配什麼飲食。就像有睡眠和心率變異性資料之後能做的那些實驗一樣。

這會把心理健康變成一個"有數字可用"的領域。布萊恩說,現在人們談心智相關的事,只能談"方式":冥想、致幻劑、某某療法。因為我們沒有大腦裡的指標可以指。我們不會說"冥想",我們會說膽固醇、動脈斑塊、心率變異性。一旦有了數字,解決方案就會對應到數字上,而不是對應到方式上。

中間萊克斯還插了一段很歡樂的追問:服 DMT 的時候會不會看見"精靈"(elves)?他有幾個奧斯汀的朋友堅信自己見過。布萊恩說自己沒親眼見過,屬於朋友的朋友的故事。萊克斯說那些精靈像愛挑刺的朋友,有點像巨魔,但又是真心希望你好。這一段恰好說明了一個問題:語言傳遞不了那個體驗,而這正是腦資料相對於文字資料的價值所在。

零階思維:比第一性原理更狠的東西

布萊恩寫過一篇文章叫《零階思維》(Zero Principle Thinking),討論人怎麼才能想出真正原創的東西。

他的區分是這樣的:第一性原理是理解系統的規律,是搭建積木;零階原理是積木本身。

他拿福爾摩斯和德克·簡特利做對比。福爾摩斯是典型的第一性原理思考者,"一旦排除了不可能,剩下的無論多麼難以置信,都是真相"。而道格拉斯·亞當斯筆下的德克·簡特利說,我不喜歡排除不可能。

這個轉折來自一本書,《零:一個危險想法的傳記》(Zero: A Biography of a Dangerous Idea)。布萊恩說這可能是他這輩子最喜歡的一本書。他之前不知道"零"這個數字是需要被發現的,也不知道它掀翻了哲學、撕裂了數學、順手建起了現代社會。它是個徹底的破壞者,社會花了很久才接受它。

零階思維對應的就是那種"零"級別的想法:現在還不存在於我們共享認知裡的東西,一旦出現,會重塑整個框架。

愛因斯坦的廣義相對論是零階的。它在牛頓的基礎上說,還有另一層,時空本身可以彎曲,整個現實的質地都變了。

AlphaGo 的棋步也是零階的。人類棋手看到那些走法,感覺像在和一個來自另一個維度的外星人下棋。那些走法本來就存在,只是剛剛進入我們的意識。

布萊恩的推論是:計算智慧天生就會產出零階洞察,那麼未來社會里零階事件的數量會變多,速度會變快。第一性原理思考沒法預測這種東西。所以他主張把零階思維放進常規的思考工具箱,它能改變個人和集體去設想哪些可能性、去談論什麼、去追求什麼。

萊克斯補了一句很關鍵的話:社會告訴你"不可能"的範圍總是劃得太寬,真正不可能的事其實很少。所以這個思考過程的核心,是把"不可能"這個集合儘量縮小。他引了喬·羅根的口頭禪:完全有可能。

意識是可以被工程化的

萊克斯說他一直在想"意識的工程學"這件事。他相信這在工程意義上是可行的,而且很難推理那會是個什麼樣的世界。

他的切入點不放在哲學上,落在人類的擬人化本能。他認為我們其實一直在對彼此做這件事:意識是在社會互動裡被創造出來的。我透過和你互動,創造了我的意識。意識的展示,跟情緒的展示是同一回事,情緒在交流中被創造,語言在使用中被創造。

那些哲學家執著於"意識的難題",他們特別想相信我們身上裝著某個叫"意識"的東西,胸口彆著名牌,專門給我們輸送主觀體驗。萊克斯的猜測是,那更像是我們為了社會溝通效率而構造出來的幻覺。

這個判斷一旦成立,工程化意識的幻覺就能在軟體裡造出非常有滿足感的體驗。

布萊恩完全同意,並且用腦機介面把它接了下去。

他先講了個反向的例子:你和我發簡訊,互相發表情包。人類互動的頻寬被壓扁了,社交線索變少,誤解的機會變多。這件事本身就在改變兩個人之間的意識體驗。

如果腦機介面加進來,溝通的維度被放大,那就是萊克斯說的"意識工程"。布萊恩舉了個具體場景:你看這個杯子,你感到快樂。你告訴我你快樂,我用心理理論去猜,萊克斯看到這個杯子時大概是什麼感覺。如果介面能給出一個五十維的向量,說這就是萊克斯看著杯子時體驗的那種快樂,我就能對你產生更深的理解和共情。你體驗快樂的方式,和我體驗快樂的方式,本來就完全不同,我們只是預設它們差不多。

再往下一步,就是人機互動。萊克斯半開玩笑地說,給 GPT-3 一堆人腦當訓練集,讓它實時閉環學習,它就能學會禮貌,學會在人類社會里找到得體的路徑。布萊恩說,那就得先決定你要哪一種 GPT-3:自由的、守規矩的、能帶回家見爸媽的,還是拉斯維加斯版的。然後你還得讓這些版本之間目標對齊,別互相操縱。

隱私:網際網路一開始就搞錯了

布萊恩對隱私問題的判斷很直接:網際網路的起點就是錯的。

當時給公司定的遊戲規則是,你能拿到多少使用者資訊就拿多少,還能誘導使用者主動交出更多,你不需要告訴他們你拿去幹什麼,你可以在後臺做任何事、賺任何錢。整個遊戲比的是誰能拿到最多資訊、誰的手段最聰明。

"那是個糟糕的起點。"(布萊恩·約翰遜)

他認為現在正處在糾偏期。正確的規則是:個人始終對自己的資料有控制權。這不能是一場"飢餓河馬"遊戲,誰手快誰搶得多。

他舉了當天錄製的例子:萊克斯的腦資料一被記錄,Kernel App 做的第一件事就是讓你控制自己的資料。個人同意、個人控制,然後才能在上面搭建別的東西。前提是規則清晰:收集了什麼、拿去做什麼、誰在什麼條款下能看到,本人都知道。

萊克斯追問:控制具體長什麼樣?能不能刪除?布萊恩說是,能刪除,能知道資料被分享給了誰、在什麼條款下。

他說現在產品的精細度還不夠。理想狀態是,你可以對 Spotify 說,你可以訪問這個向量空間模型,但只在這段時間內,用完必須刪掉。這種許可權結構今天還不存在,但必須開始討論。

布萊恩認為,一旦規則清楚、人不再容易被佔便宜,整個社會系統會穩定得多。他還預測了一個有意思的場景:未來大科技公司可能反過來向你申請訪問你的腦資料,來補全他們對你的預測模型,而你自己用 Kernel 裝置做出的自我預測,可能比他們更準。到那時候,是你在和他們談條款。

和 Neuralink 的岔路口

萊克斯把話題引到了埃隆·馬斯克和 Neuralink,那是完全相反的技術路線:侵入式、要開顱、把裝置植入大腦。

布萊恩說,他和馬斯克早期聊過很多次。當時他剛創辦 Kernel,馬斯克也對腦機介面有興趣,兩人探討過一起做,包括馬斯克加入 Kernel,最後沒有走通。之後馬斯克創辦了 Neuralink,布萊恩繼續做 Kernel。

有意思的是,兩個人的起點都是侵入式。布萊恩當時就在做侵入式技術。

轉折點是一位神經外科醫生。這位醫生做了三十年神經手術,是美國最受尊敬的神經科學家之一。Kernel 把他請來,想搞清這個行業的門道。三個小時的對話到了最後,他說了一句話。

"每隔十五年左右,就會出現一種改變一切的新技術。它很可能已經在這裡了,你只是還看不見。"(Kernel 請來的神經外科醫生)

布萊恩說他的下巴掉了。他此前已經和鮑勃·格林伯格聊過,後者先是在視神經上做陣列,後來做視皮層陣列;他也和 Neuropace 的人成了朋友,那家公司做癲癇檢測和干預的植入裝置。他親眼看到把一個植入式裝置推向市場是什麼體驗:原本以為七年,結果十五年;原本以為一億美元,結果三四億。

他其實不想做侵入式。當時看起來那是唯一可能的路。於是他在公司內部開了一個小組,專門看非侵入式方案還有沒有東西可挖。判斷標準有四條:資料質量要高、成本要低、要易得、要能讓腦機介面進入主流。

然後他做了一個押上整個公司的決定:從侵入式轉向非侵入式。

現在 Kernel 兩條路線都造出來了。布萊恩用電影打比方,幫助人理解三者的取捨:

  • Kernel Flow:你能看到完整的畫面,但影象是模糊的,聲音是悶的,覆蓋範圍廣而解析度低。
  • Kernel Flux(基於腦磁圖 MEG):你能看到完整的電影,而且是 1080p。
  • Neuralink:螢幕上只有一個小圓圈,但那個圓圈是 4K。

三條路各有取捨,談不上誰一定對。布萊恩說他賭的是 Flow 和 Flux 這兩項技術足夠支撐未來七年,並且會催生出一個比硬體本身值錢得多的生態。

他把這個生態類比成九十年代的網際網路。撥號上網能用的時候,網際網路才開始有價值;頻寬漲上去,生態跟著變好。硬體只是那扇門。他還拿 Fitbit 舉例:那家公司最終被谷歌以二十五億美元收購,但它沒有衍生生態,沒有人在上面搭東西,也沒有更多資料流進來,價值基本就停在裝置本身。蘋果不一樣,裝置有人買,生態裡有人建東西,還有新的資料流不斷加入。

布萊恩說,如果整個生態的價值是一百,Kernel 的硬體可能只佔五到十。他們真正在意的是那個生態。

關於馬斯克,他不認為是競爭對手,是同行者。網際網路剛開始的時候,有多少公司會被邀請進這個新生態?數量是無限的。

挨家挨戶賣信用卡的那九個月

要理解布萊恩後來為什麼去造腦機介面,得先回到 Braintree。

他二十一歲時剛從厄瓜多回來,在那裡和極端貧困的人一起生活了兩年。回到美國,他被這個國家的富足震住了。那一刻他決定,這輩子要試著去幫別人。具體路徑是:在三十歲前賺夠一輩子不用再工作的錢,然後用這筆錢去做那些有益於社會、但本身不成立為生意的事。

中間當然有失敗。有一次他債臺高築,需要一份兼職來付賬單。他住在猶他州,有一天在報紙上看到"猶他州五十位最富有的人",就給這五十個人的助理挨個發郵件,說自己年輕、有資源、什麼都能幹。沒有人回。他又去面試了幾十家公司,沒人願意給他時間。

最後他在 Monster 上看到一條招聘:信用卡銷售,上門推銷,純提成。

他去了。布萊恩自己說,如果應聘者能對著鏡子哈一口氣,就說明能來,因為這是百分之百提成。

他開始在社群裡沿街敲門,賣信用卡收單服務。上門的規矩他很快就摸清了:店主通常在店裡,看你一眼就能憑穿著和走路的姿態判斷出你是誰,然後立刻討厭你。就算你熬過了這一關,一說出"信用卡收單",對方更煩了,因為他被同行坑過幾十次,在他眼裡你們都是一路貨色。

布萊恩想出了一個演算法。他走進店裡,掏出一張一百美元的鈔票,說:我給你一百美元,換你三分鐘。如果你聽完不認可,這一百美元歸你。

對方通常就笑了:行啊小子,你有什麼好東西?

然後他坐下來,翻開本子講:這是信用卡行業,這是它怎麼運轉的,這些是玩家,這是他們怎麼騙你的,這是我,我跟別人沒區別。你照常收單、照常到賬,你會拿到一份乾淨的賬單,打電話有人接。就這麼基礎。

人們開始說 yes。然後他走進下一家,說,隔壁的老喬和蘇西都說 yes 了。他搭起了一個社會認同的結構。

結果他成了全國四百名銷售裡的第一名,而且還在半職做另一個創業專案。

做了九個月,他的客戶群每月產生的總營收大概是六萬兩千五百零四美元。他算了算:如果這是我自己的公司,我每個月能被動拿到六萬多美元。於是他創辦了 Braintree。

當時的市場背景是:PayPal 被 eBay 收購後基本停滯了七年,軟體世界在往前走,支付工具卻停在原地。工程師想要現代化的支付工具,市面上沒有。所以 Braintree 的切入點很明確:先做工程師會喜歡的軟體,把體驗做得漂亮、順滑,再在上面疊客戶服務。

但他真正瞄準的是 PayPal 的模型。PayPal 早期和 eBay 綁在一起,使用者用銀行賬戶給 PayPal 賬戶充值,而不是刷信用卡。使用者用 PayPal 付款給商家時,PayPal 的支付成本接近零;信用卡渠道則要給銀行交手續費。所以 PayPal 一單能賺百分之三,普通支付公司賺幾分錢。布萊恩想複製這個模型,難點在於雙邊市場很難同時建起來,之前試過的公司都失敗了。

他的計劃是分兩步:先把全世界最好的商家拿下,第五年再收購一家面向消費者的支付公司,把兩邊接起來。

這個計劃是他在芝加哥大學時就講過的。奇怪的是,它真的按原樣發生了。四年後,Braintree 的客戶裡有 Uber、Airbnb、GitHub、37signals。2012 年,他們收購了 Venmo。Venmo 做了一件反直覺的事:把原本被認為應該藏起來的私人財務往來公開化。有了 Venmo,使用者可以往賬戶裡充錢、留餘額,Venmo 也就成了支付方式。

於是 PayPal 看到了一件事:最好的商家在 Braintree,有影響力的千禧一代在用 Venmo。他們開出了一個有吸引力的價格。布萊恩的目標從來不是做全世界最大的支付公司,也不是上富豪榜。他要的是賺夠一筆錢,然後去做一件從 2050 年、2100 年、2500 年的視角看依然有價值的事。PayPal 給的錢夠他做這件事了。於是他開始系統性地盤查:全世界所有能做的事裡,哪一件對物種的價值潛力最高?

他花了一段時間才落到腦機介面上。

關於加密貨幣,布萊恩提到 Braintree 是較早把 Coinbase 整合進來的支付公司,2013 年就在做了。他認為加密貨幣背後的原則潛力很大,而且和大腦、和腦機介面與外部世界的互動、和人與人之間的目標對齊是同一套東西。他不認為錢和其他東西有什麼本質區別,錢只是整個社會的腳手架層。他看好加密技術,因為它會給腦機介面生態提供大量價值。

萊克斯順著他自己的邏輯推了一把:比特幣是不是也是對"意識心智"的降級?就像他把晚餐決策權從"夜晚的布萊恩"手裡拿走一樣。布萊恩說這個說法準確。加密貨幣是他正在構建的"自主自我"的一個版本,是一套自動化的價值交換和價值創造系統。

把大腦外包給資料:他一天只吃一頓

布萊恩的飲食方案,是幾千次實驗的結果。他每九十天做一輪測試,跑完一個週期,再測,而且平時一直在測。

他最佳化的目標很具體:完美的膽固醇、完美的血糖、完美的 DNA 甲基化過程,還要完美的睡眠。

最近兩週,他睡眠時靜息心率是 42。心率到 42 的時候,心率變異性最高,早上醒來精力比任何其他配置都好。由此他推出一個結論:早上八點半左右吃飯,剛練完、空腹狀態下吃,能讓進食結束和入睡之間拉開足夠距離,睡前幾乎不再有消化活動,靜息心率就會很低,睡眠質量就高。睡眠質量又反過來餵養意志力。睡眠、意志力、夜晚的選擇、第二天的敏感度,串成了一條迴路。

八點半他吃什麼?一碗他叫"超級蔬菜"的糊,二百五十克西蘭花、一百五十克花椰菜加一堆其他蔬菜;一碗他叫"堅果糊"的東西;第三道菜每天換,那天是羽衣甘藍、菠菜和紅薯。再加大概二十種補劑,湊一個完整的營養譜。全素。

萊克斯問好吃嗎。布萊恩說我愛它,我會夢到它。

更有意思的是他的方法論。他引用懷特海的話:文明進步的方式,是讓越來越多重要的操作可以在不思考的情況下完成。所以他的目標是造一個"完美健康演算法",自己永遠不用想它,然後這個系統能擴充套件到任何人身上。

他現在的做法是:追蹤兩百多項生物標誌物,每九十天一輪,包括完整的血液麵板、微生物組、飲食誘導的炎症反應(看細胞因子表達)、神經內分泌系統、各種神經遞質、微量營養素。然後讓資料生成購物清單。

他不再問自己的心智想吃什麼。他問的是身體想要什麼。他管這叫"布萊恩內部的目標對齊"。

"我體內有兩百多個演員,我在徵詢他們每一個人的意見。我在問我的肝臟:你還好嗎?它透過生物標誌物表達。"(布萊恩·約翰遜)

他說,這輩子讓他改變最多的,就是把意識心智從主導地位上降下來。讓意識心智掌管飲食,它會把你帶溝裡,因為它會在書架上幾十種飲食方案之間遊蕩,每一種都有配套的科學依據,卻沒有一種是針對你這個樣本量為 1 的個體。

萊克斯問,那"我感覺如何"這個主觀體驗怎麼處理?布萊恩說他做時間取樣,按一週、一個月、三個月去回看自己的感受。他不在超市貨架前取樣,不會因為"今天想吃點有趣的"就抓起一盒船長麥片。時間跨度拉長,那些自然的情緒波動就被平滑掉了,不會由某一個當下的低落來主導決策。

萊克斯說自己也是這個思路,只是更粗糙。他通常一天吃一頓,而且經常在旅行時這麼幹。他承認自己晚上自控力差,在洛杉磯吃了一頓牛腩,喝了太多無糖汽水,整晚起來上廁所,第二天一團糟。他說失敗往往來自一個雪崩效應:基本動作沒做好,其他壓力再疊上來,一天就廢了。

萊克斯還提到自己吃肉的時候感覺明顯更好,碳水吃得越多感覺越差。他說他不打算靠營養科學來支撐這個判斷,他靠的是個人經驗。營養科學很難做,因為人差異太大,心智對身體的影響也太大,很難做出真正強的研究。最好的辦法是把自己當成樣本量為 1 的科學家。

睡在辦公桌底下算不算美德

兩個人在睡眠這件事上出現了一次真正的分歧。

布萊恩認為睡眠是現存最強效的健康干預的有力競爭者,而且社會該換一套敘事。過去我們講創業者的故事,說這個人太厲害了,在辦公室待了三天,睡在桌子底下,我們覺得"哇,了不起"。他認為未來人們會覺得那是原始的,各方面都不好。

萊克斯不同意,而且很認真地反駁。他說自己在桌子底下睡過很多次,他相信混沌,相信有時候要順從熱情,去做那些不尋常的事,暫時不去最佳化健康。那是一種對自己的訊號:我把一切都扔掉了。

他承認自己有過度最佳化的恐懼。對一個程式設計師的頭腦來說,太容易把一切都算進去,結果變得過度謹慎,保守到不敢生活。他寧願死在戰鬥裡,也不願安全地待在家裡。他甚至引了《勇敢的心》裡威廉·華萊士那段演講,說每次看都會激動。

布萊恩聽完沒有反駁他的感受,而是把話題翻譯了一遍:那些話之所以打動你,是因為它觸發了某種神經遞質狀態。既然是這樣,它就可以被工程化。這並不意味著必須二選一,你可以擁有那種體驗,同時不犧牲長期健康。他相信未來的可能性正在於,我們不必接受這種取捨是必然的。

萊克斯說這確實是他自己的神經化學,他從小在蘇聯長大,在一個高度受約束的系統裡,所以對自由、對逃離控制和集權系統有極深的偏好。但他也愛嚴格,愛那種教條式的、權威式的重複習慣,因為他的身體在這種狀態下表現最好。他要的是平衡,而這個平衡最好由資料來給,而不是由他當下的感覺來定。

他還補了一句很動人的描述:思考難問題的時候,他感覺自己在調望遠鏡,閉上一隻眼,前後微調,突然瞥見那個要找的東西,但那畫面轉瞬即逝,稍微動一下就沒了。最有價值的想法都是這樣脆弱、易滑走的東西。需要一種敏感度。如果同時看手機、刷社交媒體、處理十五件事、加上昨晚沒睡好,那種敏感度就歸零了,人還能應付基本事務,但腦子裡不會產出任何有意思的東西。

布萊恩說"敏感度"這個詞抓得準。整套思路的核心就在這裡:睡眠質量決定意志力,意志力決定夜晚會不會亂吃,亂吃決定第二天的敏感度。

乞力馬紮羅:和現實的一場死鬥

那段登山經歷的背景,是布萊恩人生最黑暗的時期。他正在結束一段十三年的婚姻,正在離開自己出生就被灌輸的宗教,剛賣掉 Braintree,同時在和抑鬱症搏鬥,已經到極限了。

他被邀請去坦尚尼亞,作為一支為修建淨水井籌款的隊伍成員。他捐了兩萬五千美元,那是他第一次在繳納宗教什一稅之外有錢可捐。看到正在修建的水井,和當地人交談,這件事讓他很有能量。然後他們去爬乞力馬紮羅。

第三天他得了腸胃型流感,同時還有高原反應。到第五天,他走進海拔一萬五千英尺的營地時,已經控制不住身體,摔得到處都是。他還有三個年幼的孩子。他說那段時間他感覺像被綁在束身衣裡:要不要活下去已經不完全由他自己決定了,他和三個小人綁在了一起,無論喜不喜歡,他必須在那裡。

午夜,嚮導進來問他狀態。他說,我想我可以試試。他們從午夜出發,清晨五點登頂。

那是他人生中最具轉化性的時刻之一。山變成了他的問題本身,變成了他所有掙扎的化身。疼痛劇烈到某個程度,他把音樂切到 Eminem。他說,Eminem 是唯一一個能跟他靈魂對話的人,那種憤怒和生命力讓他稍微喘得過氣。

離山頂還有一百碼,他開始頭暈,覺得自己會從旁邊的崖壁往後栽下去。嚮導艾克說,布萊恩,我知道你在什麼狀態,我知道你能行。抬頭,邁一步,呼吸,抬頭,邁一步,呼吸。他就這麼走完了。

到了頂上,他坐在嚮導身邊,像個嬰兒一樣哭。哭完,嚮導掏出脈搏血氧儀測了一下,血氧大約五十幾個百分點,是危險區。沒有直升機,沒法緊急撤離,只能走下去,走回一萬五千英尺的營地。

下山也極難。後來他們把他放上一個帶單輪的金屬擔架,六個人推著他往下走,走了好幾個小時。路很顛,他的頭每隔幾秒就撞一下金屬,加上本來就難受,整個過程非常折磨。

他說,那是他重建人生的分界線。他決定重構布萊恩這個人:對現實的理解、存在層面的設定、要追求什麼。他儘可能徹底地重來一遍。

萊克斯問,是那種掙扎本身起作用嗎?一個人帶著身心痛苦往山上爬,對抗比自己大得多的自然。布萊恩說,他當時感覺是和現實鎖在了一起,是一場死鬥,那一刻,兩個人裡有一個會死。登頂意味著"我會贏,我能做到",放棄意味著"我完了"。

他說山對他有魔力。這不是他設計出來的,也不是他能預料的。

聽建議,但別照著做

萊克斯請布萊恩給年輕人一些建議,關於職業、關於人生。

布萊恩的回答很特別:聽建議,但把它當成那個人的一面鏡子,並且要知道,你的未來落在零階的地界裡。今天你聽到的東西,反映的可能是過去適用的原則,而這些原則正在快速貶值。

他說自己是"求建議但不採納建議"的堅定支持者。正確用法是把重點放在理解那個人搭建的假設棧上,照做本身沒什麼價值。價值在於搞清楚他在這條建議背後堆疊了多少假設和知識。

"價值不在於照他說的做。價值在於理解他圍繞那套知識搭建的假設棧。"(布萊恩·約翰遜)

建議只是冰山露出水面的一角。同樣一條建議,取決於底下的假設棧,可能完全正確,也可能完全錯誤。所以要考察整座冰山。

萊克斯接著說了另一面:給建議的人也要有足夠的共情。一個十八歲的年輕人走過來,你很難一眼看清他是誰,不能只聽到他說的事實,要看到那個人本身。他提到做父母也是這樣,不要當權威角色,要意識到那裡有一個獨特的人,大腦構造和你不同,可能有些地方比你聰明,只是你看不懂。

布萊恩說,他記憶裡最重要的那些時刻,都來自這種一對一的深度共情。乞力馬紮羅上的艾克,一個他在坦尚尼亞從沒見過的人,在他和現實死斗的那一刻,彷彿看見了他的靈魂,然後給了他"抬頭、邁步"這樣的指令。他說他應該更擅長識別這類時刻,也希望自己有朝一日能有那種覺察和共情,成為別人生命裡的那種人,而不做一個兜售人生技巧的零售廣告商。

智慧的成本正在歸零

萊克斯問,這一切的意義到底是什麼,我們為什麼在這裡。

布萊恩先給了一個前提:這個問題本身有資訊量,但資訊量更多在於它像一面鏡子,照出提問者所處的技術、社會、政治語境。一百年前問,會得到一百年前的答案;一千年前問,會得到一千年前的答案。一個人很難把自己從語境裡拔出來,給出真正原創的回答。

在此之上,他給了三個層次。

第一層:進化構建了一套搭建智慧的腳手架系統,造出了我們。我們現在正在構建智慧系統,去搭建更高維的智慧,去發展更穩健的智慧體系。這個過程裡,智慧的設計、製造、分發成本正在走向零。

第二層:當成本歸零,生命的意義就變成目標對齊,也就是對我們意識和無意識存在的協商。

第三層:如果我們自認是探索者,那麼技術進展會帶來一個機會:人類可以抱有一個願望,去搞清楚"到底真正在發生什麼"。也許我們離戳破這一層還有一百年、兩百年、五百年、一千年,但至少這個願望可以被提出來。

他還引了詹姆斯·卡斯的《有限與無限的遊戲》。他說,眼下唯一值得玩的遊戲,就是把遊戲繼續玩下去。放到他和萊克斯前面聊的牛腩和無糖汽水上,這個結論很實用:既然可能性變化的速率這麼快,舊的風險評估演算法和舊的目標假設可能很快失效,那麼在權衡時,稍微偏向"確保自己還在牌桌上"是划算的。

抑鬱是生化狀態,不是你

萊克斯問了一個很直接的問題:大腦終將停止,你會死,那個資料來源會比你想的更早下線,這件事會讓你難過嗎?

布萊恩說這是個複雜的問題,不同的人生階段他會有不同的答案。他有過十年慢性抑鬱。在那十年裡,他極度渴望把燈關掉。更糟的是,他出生在一個宗教裡,那是他唯一理解過的現實,他被徹底擋在其他現實之外,因為那是典型的圈內圈外結構。他不僅絕望地不想存在,還被告知不能不存在,因為有來世,有獎懲系統。他說那是一種無法形容的絕望:既不想活,又被強制活著。

也有別的時期。他望著未來,覺得那是一個超越他理解能力的、進化中的未來意識體驗的機會,他會從床上一躍而起,衝向工作,別的什麼都想不了。

但他對這件事的最終態度是:他不相信自己的回答。他描述自己早晨醒來時,腦子裡沒有一個溫和的"早上好,布萊恩"。那裡是"你沒把昨天的事重演四百遍嗎,你沒把人生所有遺憾再放一遍嗎"。他說他的大腦內部是個殘酷的環境,我們已經對此麻木,把它當成做人的預設設定,但如果嚴肅地審視,做人這件事是殘酷的。

他這輩子換過好幾個現實。宗教那個現實是款電子遊戲,後來他發現不是真的;抑鬱那個現實帶來可怕的絕望,也不是真的;再後來他學了行為心理學,知道了認知偏差,明白大腦一直在扭曲現實。他說他不信任現實,不信任被給予的現實。

所以他的做法是:假設意識心智交給覺察的任何東西,在落地那一刻就是錯的。他只需要搞清楚錯在哪、錯多少,然後儘量修正。

萊克斯問他怎麼應對那些黑暗時刻,也問他能給正在經歷這些的人什麼建議。

布萊恩說了兩件事。第一,那些抑鬱狀態是生化狀態,那狀態不是你。那種狀態告訴你的一切,關於人生毫無意義、關於該按下彈出鍵,都是假的現實。他完全理解一個人選擇自殺的理性邏輯,那不是他不明白的事。要點是,當那些念頭落地的時候,能說一句:謝謝,你不是真的,我知道你不是真的。我現在處在某個神經化學狀態裡,但這個狀態可以被改變。

萊克斯在另一頭補充了自己的版本。他說自己是個非常幸運的人,一天裡會好幾次,看著一個杯子就被巨大的喜悅擊中,覺得活著太不可思議了。他說這完全不合理,不符合他生活裡的其他部分。他自我批判到幾乎討厭自己做的每件事,總是遲到,但外面有一臺喜悅的發動機,跟這些無關。他認為那一定是化學。而抑鬱大概就是那件事的反面。

他說,那種"杯子太美了"的感受,大概能救任何一個陷在抑鬱狀態裡的人,就像沙漠裡的一口水。他很想知道那感受從哪來,想知道怎麼在高低起伏之間找到那條線。

布萊恩把這接回了他的核心命題:人類認知是社會里最大宗的原材料輸入,卻沒有被量化,我們對自己沒有方位感。兩個人各自描述了自己頭腦裡的困境,很可能很多人會說"我也差不多"。那麼問題就是:這件事在多大程度上加重了社會正在經歷的其他複合問題?在多大程度上讓人對眼前的機會視而不見?它有一種對現實的扭曲效應,會把一切都變得更糟。如果給這些東西配上數字,哪怕只是找到方位感,也許就能給個人生活和制度建設帶來更大的穩定性,進而支撐起下一步的腳手架。

人類在系統性地搭建技術、科學和制度這件事上做得非常出色。現在剩下的,是把自己也搭進去。

"我們的大腦是一座擁擠的化學實驗室,無休止的神經對話在其中喧鬧。"(黛安·阿克曼)

如果把這場對話壓縮成幾句對個人有用的東西,大概是這些:

  • 把自己當成樣本量為 1 的受試者。飲食、睡眠、情緒、專注度,先做時間取樣,按周、按月記錄,再讓資料生成決策,別讓某一個當下的狀態替你拍板。
  • 給心智的即時輸出設一道預設懷疑。它交上來的結論,先假定它在某些關鍵處是錯的,再去找錯在哪,而不是先假定它對。
  • 把重要決策和瞬時狀態解耦。晚上意志力低的時候不做長期決策,餓的時候不去想未來,情緒低谷時不評估人生價值。
  • 區分生化狀態和你自己。低谷來臨時,先承認它是一個可以改變的生理狀態,而不是關於世界真相的可靠報告。
  • 聽建議時考察整座冰山。不要照做,去挖那個人背後的假設棧,理解他為什麼得出這個結論,然後判斷它在你的情境裡是否成立。
  • 別把"不可能"這個集合劃得太寬。真正不可能的事比你以為的少,把精力放在縮小這個集合上。
  • 在過度最佳化和擁抱生活之間留一條縫。長期健康的目標和偶爾的放縱不必然是取捨,把它們當成兩個可以同時滿足的約束去解。
  • 保住自己在牌桌上。既然技術變化的速度遠快於任何一套舊的風險評估模型,那麼在權衡時偏向"確保還能繼續玩下去"是划算的。

The following is a conversation with Brian Johnson, founder of Kernel, a company that has developed devices that can monitor and record brain activity. And previously, he was the founder of Braintree, a mobile payment company that acquired Venmo and then was acquired by PayPal and eBay. Quick mention of our sponsors, Forsigmatic, NetSuite, Grammarly, and ExpressVPN. Check them out in the description to support this podcast. As a side note, let me say that this was a fun and memorable experience, wearing the Kernel FlowBrain interface in the beginning of this conversation, as you can see if you watch the video version of this episode. And there was a Ubuntu Linux machine sitting next to me collecting the data from my brain. The whole thing gave me hope that the mystery of the human mind will be unlocked in the coming decades as we begin to measure signals from the brain in a high bandwidth way. To understand the mind, we either have to build it or to measure it. Both are worth a try. Thanks to Brian and the rest of the Kernel team for making this little demo happen. This is the Lex Friedman Podcast, and here is my conversation with Brian Johnson. You ready, Lex? Yes, I'm ready. Do you guys wanna come in and put the interfaces on our heads? And then I will proceed to tell you a few jokes. So we have two incredible pieces of technology and a machine running Ubuntu 2004 in front of us. What are we doing? All right. Are these going on our heads? They're going on our heads, yeah. And they will place it on our heads for proper alignment. Does this support giant heads? Because I kind of have a giant head. Is this just giant head? Are you saying as like an ego or are you saying physically both? It's a nice massage. Yes. Okay, how does this feel? It's okay to move around? Yeah. It feels, oh yeah. Hey, hey. This feels awesome. It's a pretty good fit. Thank you. That feels good. So this is big head friendly. It suits you well, Lex. Thank you. I feel like I need to, I feel like when I wear this, I need to sound like Sam Harris, calm, collected, eloquent. I feel smarter, actually. I don't think I've ever felt quite as much like I'm part of the future as now. Have you ever worn a brain interface or had your brain imaged? Oh, never had my brain imaged. The only way I've analyzed my brain is by talking to myself and thinking. No direct data. Yeah, that is definitely a brain interface that has a lot of blind spots. It has some blind spots, yeah. Psychotherapy. That's right. All right, are we recording? Yeah, we're good. All right. So Lex, the objective of this, I'm going to tell you some jokes and your objective is to not smile, which as a Russian, you should have an edge. Make the motherland proud. I gotcha. Okay. Let's hear the jokes. Lex, and this is from the Colonel Crew. We've been working on a device that can read your mind and we would love to see your thoughts. Is that the joke? That's the opening. Okay. If I'm seeing the muscle activation correctly on your lips, you're not going to do well on this. Let's see. All right, here comes the first. I'm screwed. Here comes the first one. Is this going to break the device? Is it resilient to laughter? Lex, what goes through a potato's brain? I can't. I got already failed. That's the hilarious opener. Okay. What? Tater thoughts. What kind of fish performs brain surgery? I don't know. A neural surgeon. And so we're getting data of everything that's happening in my brain right now? Lifetime, yeah. We're getting activation patterns of your entire cortex. I'm going to try to do better. I'll edit out all the parts where I laughed. Photoshop put a serious face over me. You can recover. Yeah, all right. Lex, what do scholars eat when they're hungry? I don't know, what? Academia nuts. That was a pretty good one. So what we'll do is, so you're wearing kernel flow, which is an interface built using technology called spectroscopy. So it's similar to what we wear wearables on the wrist using light. So using LIDAR, as you know, and we're using that to image the functional imaging of brain activity. And so as your neurons fire electrically and chemically, it creates blood oxygenation levels. We're measuring that. And so you'll see in the reconstructions we do for you, you'll see your activation patterns in your brain as throughout this entire time we are wearing it. So in the reaction to the jokes and as we were sitting here talking, and so we're moving towards a real time feed of your cortical brain activity. So there's a bunch of things that are in contact with my skull right now. How many of them are there? And so how many of them are, what are they? What are the actual sensors? There's 52 modules, and each module has one laser and six sensors. And the sensors fire in about 100 picoseconds. And then the photons scatter and absorb in your brain. And then a few go in, a few come back out, a bunch go in, then a few come back out, and we sense those photons and then we do the reconstruction for the activity. Overall, there's about a thousand plus channels that are sampling your activity. How difficult is it to make it as comfortable as it is? Because it's surprisingly comfortable. I would not think it would be comfortable. Something that's measuring brain activity, I would not think it would be comfortable, but it is. I agree. In fact, I want to take this home. Yeah, yeah, that's right. So people are accustomed to being in big systems like fMRI where there's 120 decibel sounds and you're in a claustrophobic encasement, or EEG, which is just painful, or surgery. And so, yes, I agree that this is a convenient option to be able to just put on your head that measures your brain activity in the contextual environment you choose. So if we want to have it during a podcast, if we want to be at home in a business setting, it's freedom to record your brain activity in the setting that you choose. Yeah, but sort of from an engineering perspective, are these, what is it? There's a bunch of different modular parts and they're kind of, there's like a rubber band thing where they mold to the shape of your head. That's right. So we built this version of the mechanical design to accommodate most adult heads. But I have a giant head and it fits fine. It fits well, actually. So I don't think I have an average head. Okay, maybe I feel much better about my head now. Maybe I'm more average than I thought. Okay, so what else is there interesting that you could say while it's on our heads? I can keep this on the whole time. This is kind of awesome. And it's amazing for me, as a fan of Ubuntu, I use Ubuntu MATE, you guys use that too. But it's amazing to have code running to the side, measuring stuff and collecting data. I mean, I feel like much more important now that my data is being recorded. Like, you know when you have a good friend that listens to you, that actually is listening to you? This is what I feel like, like a much better friend because it's like accurately listening to me, Ubuntu. What a cool perspective, I hadn't thought about that, of feeling understood. Heard. Yeah, heard deeply by the mechanical system that is recording your brain activity, versus the human that you're engaging with, that your mind immediately goes to that there's this dimensionality and depth of understanding of this software system which you're intimately familiar with. And now you're able to communicate with this system in ways that you couldn't before. Yeah, I feel heard. Yeah, I mean, I guess what's interesting about this is your intuitions are spot on. Most people have intuitions about brain interfaces that they've grown up with this idea of people moving cursors on the screen or typing or changing the channel or skipping a song. It's primarily been anchored on control. And I think the more relevant understanding of brain interfaces or neuroimaging is that it's a measurement system. And once you have numbers for a given thing, a seemingly endless number of possibilities emerge around that of what to do with those numbers. So before you tell me about the possibilities, this was an incredible experience. I can keep this on for another two hours, but I'm being told that for a bunch of reasons, just because we probably wanna keep the data small and visualize it nicely for the final product, we wanna cut this off and take this amazing helmet away from me. So Brian, thank you so much for this experience and let's continue without helmetless. All right. So that was an incredible experience. Can you maybe speak to what kind of opportunities that opens up that stream of data, that rich stream of data from the brain? First, I'm curious, what is your reaction? What comes to mind when you put that on your head? What does it mean to you? And what possibilities emerge and what significance might it have? I'm curious where your orientation is at. Well, for me, I'm really excited by the possibility of various information about my body, about my mind being converted into data, such that data can be used to create products that make my life better. So that to me is really exciting possibility. Even just like a Fitbit that measures, I don't know, some very basic measurements about your body is really cool. But the bandwidth of information, the resolution of that information is very crude, so it's not very interesting. The possibility of just building a data set coming in a clean way and a high bandwidth way from my brain opens up all kinds of... I was kind of joking when we were talking, but it's not really, it's like I feel heard in the sense that it feels like the full richness of the information coming from my mind is actually being recorded by the machine. I mean, I can't quite put it into words, but there is genuinely for me, there's not some kind of joke about me being a robot. It just genuinely feels like I'm being heard in a way that's going to improve my life, as long as the thing that's on the other end can do something useful with that data. But even the recording itself is like, once you record, it's like taking a picture. That moment is forever saved in time. Now, a picture cannot allow you to step back into that world, but perhaps recording your brain is a much higher resolution thing, much more personal recording of that information than a picture that would allow you to step back into that where you were in that particular moment in history and then map out a certain trajectory to tell you certain things about yourself that could open up all kinds of applications. Of course, there's health that I consider, but honestly, to me, the exciting thing is just being heard. My state of mind, the level of focus, all those kinds of things, being heard. What I heard you say is you have an entirety of lived experience, some of which you can communicate in words and in body language, some of which you feel internally, which cannot be captured in those communication modalities, and that this measurement system captures both the things you can try to articulate in words, maybe in a lower dimensional space, using one word, for example, to communicate focus, when it really may be represented in a 20 dimensional space of this particular kind of focus and that this information is being captured, so it's a closer representation to the entirety of your experience captured in a dynamic fashion that is not just a static image of your conscious experience. Yeah, that's the promise, that was the feeling, and it felt like the future. So it was a pretty cool experience. And from the sort of mechanical perspective, it was cool to have an actual device that feels pretty good, that doesn't require me to go into the lab. And also the other thing I was feeling, there's a guy named Andrew Huberman, he's a friend of mine, amazing podcast, people should listen to it, Huberman Lab Podcast. We're working on a paper together about eye movement and so on. And we're kind of, he's a neuroscientist and I'm a data person, machine learning person, and we're both excited by how much the, how much the data measurements of the human mind, the brain and all the different metrics that come from that could be used to understand human beings and in a rigorous scientific way. So the other thing I was thinking about is how this could be turned into a tool for science. Sort of not just personal science, not just like Fitbit style, like how am I doing on my personal metrics of health, but doing larger scale studies of human behavior and so on. So like data, not at the scale of an individual, but data at a scale of many individuals or a large number of individuals. So personal being heard was exciting and also just for science is exciting. It's very easy, like there's a very powerful thing to it being so easy to just put on that you could scale much easier. If you think about that second thing you said about the science of the brain, most, we've done a pretty good job, like we, the human race has done a pretty good job figuring out how to quantify the things around us from distant stars to calories and steps and our genome. So we can measure and quantify pretty much everything in the known universe except for our minds. And we can do these one offs if we're going to get an fMRI scan or do something with a low res EEG system, but we haven't done this at population scale. And so if you think about human thought or human cognition is probably the single law, largest raw input material into society at any given moment is our conversations with ourselves and with other people. And we have this raw input that we can't, that haven't been able to measure yet. And if you, when I think about it through that frame, it's remarkable, it's almost like we live in this wild, wild West of unquantified communications within ourselves and between each other when everything else has been grounded in me. For example, I know if I buy an appliance at the store or on a website, I don't need to look at the measurements on the appliance and make sure it can fit through my door. That's an engineered system of appliance manufacturing and construction. Everyone's agreed upon engineering standards. And we don't have engineering standards around cognition. It's not a, it has not entered as a formal engineering discipline that enables us to scaffold in society with everything else we're doing, including consuming news, our relationships, politics, economics, education, all the above. And so to me that the most significant contribution that kernel technology has to offer would be the formal, the introduction to formal engineering of cognition as it relates to everything else in society. I love that idea that you kind of think that there's just this ocean of data that's coming from people's brains as being in a crude way, reduced down to like tweets and texts and so on, just a very hardcore, many scale compression of actual, the raw data. But maybe you can comment, because you're using the word cognition. I think the first step is to get the brain data. But is there a leap to be taking to sort of interpreting that data in terms of cognition? So is your idea is basically you need to start collecting data at scale from the brain, and then we start to really be able to take little steps along the path to actually measuring some deep sense of cognition. Because as I'm sure you know, we understand a few things, but we don't understand most of what makes up cognition. This has been one of the most significant challenges of building Kernel, and Kernel wouldn't exist if I wasn't able to fund it initially by myself. Because when I engage in conversations with investors, the immediate thought is, what is the killer app? And of course, I understand that heuristic, that's what they're looking at, is they're looking to de risk. Is the product solved? Is there a customer base? Are people willing to pay for it? How does it compare to competing options? And in the case with brain interfaces, when I started the company, there was no known path to even build a technology that could potentially become mainstream. And then once we figured out the technology, we could even, we could commence having conversations with investors and it became, what is the killer app? And so what has been, so I funded the first $53 million for the company. And to raise the round of funding, the first one we did, I spoke to 228 investors. One said yes, it was remarkable. And it was mostly around this concept around what is a killer app. And so internally, the way we think about it is, we think of the go to market strategy much more like the Drake equation, where if we can build technology It's human, it's our own selves, which we have not been able to scaffold. We are the one part of this intelligence infrastructure that remains unchanged. Is there something you could say about coupling this brain data with not just the basic human experience, but say an experience, you mentioned sleep, but the wildest experience, which is psychedelics, is there, and there's been quite a few studies now that are being approved and run, which is exciting from a scientific perspective on psychedelics. Do you think, what do you think happens to the brain on psychedelics? And how can data about this help us understand it? And when you're on DMT, do you see Ls? And can we convert that into data? Can you add aliens in there? Yeah, aliens, definitely. Do you actually meet aliens? And Ls, are Ls the aliens? I'm asking for a few Austin friends, yeah, that are convinced that they've actually met the Ls. What are Ls like? Are they friendly? Are they help? I haven't met them personally. Are they like the smurfs of like they're industrious and they have different skill sets and? Yeah, I think they're very, they're very critical as friends. They're trolls. The Ls are trolls. No, but they care about you. So there's a bunch of different version of trolls. There's loving trolls that are harsh on you, but they want you to be better. And there's trolls that just enjoy your destruction. And I think they're the ones that care for you. I think they're a criticism for my, see, I haven't met them directly, so it's like a friend of a friend. Yeah, they gave him a telephone. Yeah, a bit of a, and the whole point is that in psychedelics, and certainly at DMT, word, this is where the brain data versus word data fails, which is, you know, words can't convey the experience. Most people that, you can be poetic and so on, but it really does not convey the experience of what it actually means to meet the Ls. I mean, to me, what baselines this conversation is, imagine if we were interested in the health of your heart, and we started and said, okay, Lex, self interest back, tell me how's the health of your heart. And you sit there and you close your eyes and you think, feels all right, like things feel okay. And then you went to the cardiologist and the cardiologist is like, hey Lex, you know, tell me how you feel. You're like, well, actually, what I'd really like you to do is do an EKG and a blood panel and look at arterial plaques and let's look at my cholesterol. And there's like five to 10 studies you would do. They would then give you this report and say, here's the quantified health of your heart. Now with this data, I'm going to prescribe the following regime of exercise and maybe I'll put you on a statin, like, et cetera. But the protocol is based upon this data. You would think the cardiologist is out of their mind if they just gave you a bottle of statins based upon, you're like, well, I think something's kind of wrong. And they're just kind of experiment and see what happens. But that's what we do with our mental health today. So it's kind of absurd. And so if you look at psychedelics to have, again, to be able to measure the brain and get a baseline state, and then to measure during a psychedelic experience and post the psychedelic experience and then do it longitudinally, you now have a quantification of what's going on. And so you could then pose questions, what molecule is appropriate at what dosages, at what frequency, in what contextual environment, what happens when I have this diet with this molecule, with this experience, all the experimentation you do when you have good sleep data or HRV. And so that's what I think happens, what we could potentially do with psychedelics is we could add this level of sophistication that is not in the industry currently. And it may improve the outcomes people experience, it may improve the safety and efficacy. And so that's what I hope we are able to achieve. And it would transform mental health because we would finally have numbers to work with to baseline ourselves. And then if you think about it, when we talk about things related to the mind, we talk about the modality. We use words like meditation or psychedelics or something else, because we can't talk about a marker in the brain. We can't use a word to say, we can't talk about cholesterol. We don't talk about plaque in the arteries. We don't talk about HRV. And so if we have numbers, then the solutions get mapped to numbers instead of the modalities being the thing we talk about. Meditation just does good things in a crude fashion. So in your blog post, Zero Principle Thinking, good title, you ponder how do people come up with truly original ideas. What's your thoughts on this as a human and as a person who's measuring brain data? Zero principles are building blocks. First principles are understanding of system laws. So if you take, for example, like in Sherlock Holmes, he's a first principles thinker. So he says, once you've eliminated the impossible, anything that remains, however improbable, is true. Whereas Dirk Gently, the holistic detective by Douglas Adams says, I don't like eliminating the impossible. So when someone says, from a first principles perspective, and they're trying to assume the fewest number of things within a given timeframe. And so when I, after Braintree Venmo, I set my mind to the question of, what single thing can I do that would maximally increase the probability that the human race thrives beyond what we can even imagine? And I found that in my conversations with others in the books I read, in my own deliberations, I had a missing piece of the puzzle, because I didn't feel like, yeah, I didn't feel like the future could be deduced from first principles thinking. And that's when I read the book, Zero, A Biography of a Dangerous Idea. And I... It's a really good book, by the way. I think it's my favorite book I've ever read. It's also a really interesting number, zero. And I wasn't aware that the number zero had to be discovered. I didn't realize that it caused a revolution in philosophy and just tore up math and it tore up, I mean, it builds modern society, but it wrecked everything in its way. It was an unbelievable disruptor, and it was so difficult for society to get their heads around it. And so zero is, of course, the representation of a zero principle thinking, which is it's the caliber and consequential nature of an idea. And so when you talk about what kind of ideas have civilization transforming properties, oftentimes they fall in the zeroth category. And so in thinking this through, I was wanting to find a quantitative structure on how to think about these zeroth principles. And that's, so I came up with that to be a coupler with first principles thinking. And so now it's a staple as part of how I think about the world and the future. So it emphasizes trying to identify, it lands on that word impossible. Like what is impossible, essentially trying to identify what is impossible and what is possible. And being as, how do you, I mean, this is the thing, is most of society tells you the range of things they say is impossible is very wide. So you need to be shrinking that. I mean, that's the whole process of this kind of thinking is you need to be very rigorous in thinking about and be very rigorous in trying to be, trying to draw the lines of what is actually impossible because very few things are actually impossible. I don't know what is actually impossible. Like it's the Joe Rogan, it's entirely possible. I like that approach to science, to engineering, to entrepreneurship, it's entirely possible. Basically shrink the impossible to zero, to a very small set. Yeah, life constraints favor first principle thinking because it enables faster action with higher probability of success. Pursuing zero with principle optionality is expensive and uncertain. And so in a society constrained by resources, time and money and a desire for social status, accomplishment, et cetera, it minimizes zero with principle thinking. But the reason why I think zero with principle thinking should be a staple of our shared cognitive infrastructure is if you look through the history of the past couple of thousand years and let's just say we arbitrarily, we subjectively try to assess what is a zero level idea. And we say how many have occurred on what time scales and what were the contextual settings for it? I would argue that if you look at AlphaGo, when it played Go from another dimension, with the human Go players, when it saw AlphaGo's moves, it attributed to like playing with an alien, playing Go with AlphaGo being from another dimension. And so if you say computational intelligence has an attribute of introducing zero like insights, then if you say what is going to be the occurrence of zeros in society going forward? And you could reasonably say probably a lot more than have occurred and probably more at a faster pace. So then if you say, what happens if you have this computational intelligence throughout society that the manufacturing design and distribution of intelligence is now going to heading towards zero, you have an increased number of zeros being produced with a tight connection between human and computers. That's when I got to a point and said, we cannot predict the future with first principles thinking. We can't, that cannot be our imagination set. It can't be our sole anchor in the situation that basically the future of our conscious existence, 20, 30, 40, 50 years is probably a zero. So just to clarify, when you say zero, you're referring to basically a truly revolutionary idea. Yeah, something that is currently not a building block of our shared conscious existence, either in the form of knowledge. Yeah, it's currently not manifest in what we acknowledge. So zero principle thinking is playing with ideas that are so revolutionary that we can't even clearly reason about the consequences once those ideas come to be. Yeah, or for example, like Einstein, that was a zeroeth, I would categorize it as a zeroeth principle insight. You mean general relativity, space time. Yeah, space time, yep, yep. That basically building upon what Newton had done and said, yes, also, and it just changed the fabric of our understanding of reality. And so that was unexpected, it existed. We just, it became part of our awareness and the moves AlphaGo made existed. It just came into our awareness. And so to your point, there's this question of what do we know and what don't we know? Do we think we know 99% of all things or do we think we know 0.001% of all things? And that goes back to no known, no unknowns and unknown unknowns. And first principles and zero principle thinking gives us a quantitative framework to say, there's no way for us to mathematically try to create probabilities for these things. Therefore, it would be helpful if they were just part of our standard thought processes because it may encourage different behaviors in what we do individually, collectively as a society, what we aspire to, what we talk about, the possibility sets we imagine. Yeah, I've been engaged in that kind of thinking quite a bit and thinking about engineering of consciousness. I think it's feasible, I think it's possible in the language that we're using here. And it's very difficult to reason about a world when inklings of consciousness can be engineered into artificial systems. Not from a philosophical perspective, but from an engineering perspective, I believe a good step towards engineering consciousness is creating engineering the illusion of consciousness. So I'm captivated by our natural predisposition to anthropomorphize things. And I think that's what we, I don't wanna hear from the philosophers, but I think that's what we kind of do to each other. That consciousness is created socially, that like much of the power of consciousness is in the social interaction. I create your consciousness, no, I create my consciousness by having interacted with you. And that's the display of consciousness. It's the same as like the display of emotion. Emotion is created through communication. Language is created through its use. And then we somehow humans kind of, especially philosophers, the hard problem of consciousness or the hard problem of consciousness, really wanna believe that we possess this thing. That's like there's an elf sitting there with a hat or like name tag says consciousness, and they're like feeding this subjective experience to us as opposed to like it actually being an illusion that we construct to make social communication more effective. And so I think if you focus on creating the illusion of consciousness, you can create some very fulfilling experiences in software. And so that to me is a compelling space of ideas to explore. I agree with you. And I think going back to our experience together with Brain Interfaces on, you could imagine if we get to a certain level of maturity. So first let's take the inverse of this. So you and I text back and forth and we're sending each other emojis. That has a certain amount of information transfer rate as we're communicating with each other. And so in our communication with people via email and texts and whatnot, we've taken the bandwidth of human interaction, the information transfer rate, and we've reduced it. We have less social cues. We have less information to work with. There's a lot more opportunity for misunderstanding. So that is altering the conscious experience between two individuals. And if we add Brain Interfaces to the equation, let's imagine now we amplify the dimensionality of our communications. That to me is what you're talking about, which is consciousness engineering. Perhaps I understand you with dimensions. So maybe I understand your, when you look at the cup and you experience that happiness, you can tell me you're happy. And I then do theory of mine and say, I can imagine what it might be like to be Lex and feel happy about seeing this cup. But if the interface could then quantify and give me a 50 vector space model and say, this is the version of happiness that Lex is experiencing as he looked at this cup, then it would allow me potentially to have much greater empathy for you and understand you as a human. This is how you experience joy, which is entirely unique from how I experienced joy, even though we assumed ahead of time that we're having some kind of similar experience. But I agree with you that we do consciousness engineering today in everything we do. When we talk to each other, when we're building products and that we're entering into a stage where it will be much more methodical and quantitative based and computational in how we go about doing it. Which to me, I find encouraging because I think it creates better guardrails to create ethical systems versus right now, I feel like it's really a wild, wild west on how these interactions are happening. Yeah, and it's funny you focus on human to human, but that this kind of data enables human to machine interaction, which is what we're kind of talking about when we say engineering consciousness. And that will happen, of course, let's flip that on its head. Right now we're putting humans as the central node. What if we gave GPT3 a bunch of human brains and said, hey, GPT3, learn some manners when you speak. Yeah. And run your algorithms on humans brains and see how they respond. So you can be polite and so that you can be friendly and so that you can be conversationally appropriate, but to inverse it, to give our machines a training set in real time with closed loop feedback so that our machines were better equipped to find their way through our society in polite and kind and appropriate ways. I love that idea. Or better yet, teach it some, have it read the following documents and have it visit Austin and Texas. And so that when you ask, when you tell it, why don't you learn some manners, GPT3 learns to say no. It learns what it means to be free and a sovereign individual. So that, it depends. So it depends what kind of a version of GPT3 you want. One that's free, one that behaves well with the social. Viva la revolution. You want a socialist GPT3, you want an anarchist GPT3, you want a polite, like you take it home to visit mom and dad GPT3 and you want like party and like Vegas to a strip club GPT3, you want all flavors. And then you've gotta have goal alignment between all those. Yeah, they don't want to manipulate each other for sure. So that's, I mean, you kind of spoke to ethics. One of the concerns that people have in this modern world, the digital data is that of privacy and security. But privacy, they're concerned that when they share data, it's the same thing with you when we trust other human beings in being fragile and revealing something that we're vulnerable about. There's a leap of faith, there's a leap of trust that that's going to be just between us. There's a privacy to it. And then the challenge is when you're in the digital space then sharing your data with companies that use that data for advertisement and all those kinds of things, there's a hesitancy to share that much data, to share a lot of deep personal data. And if you look at brain data, that feels a whole lot like it's richly, deeply personal data. So how do you think about privacy with this kind of ocean of data? I think we got off to a wrong start with the internet where the basic rules of play for the company that be was, if you're a company, you can go out and get as much information on a person as you can find without their approval. And you can also do things to induce them to give you as much information. And you don't need to tell them what you're doing with it. You can do anything on the backside, you can make money on it, but the game is who can acquire the most information and devise the most clever schemes to do it. That was a bad starting place. And so we are in this period where we need to correct for that. And we need to say, first of all, the individual always has control over their data. It's not a free for all. It's not like a game of hungry hippo, but they can just go out and grab as much as they want. So for example, when your brain data was recorded today, the first thing we did in the kernel app was you have control over your data. And so it's individual consent, it's individual control. And then you can build up on top of that, but it has to be based upon some clear rules of play if everyone knows what's being collected, they know what's being done with it, and the person has control over it. So transparency and control. So everybody knows what does control look like, my ability to delete the data if I want. Yeah, delete it and to know who is being shared with under what terms and conditions. We haven't reached that level of sophistication with our products of if you say, for example, hey Spotify, please give me a customized playlist according to my neurome, you could say, you can have access to this vector space model, but only for this duration of time and then you've got to delete it. We haven't gotten there to that level of sophistication, but these are ideas we need to start talking about of how would you actually structure permissions? Yeah. And I think it creates a much more stable set for society to build where we understand the rules of play and people aren't vulnerable to being taken advantage. It's not fair for an individual to be taken advantage of without their awareness with some other practice that some company is doing for their sole benefit. And so hopefully we are going through a process now where we're correcting for these things and that it can be an economy wide shift that, because really these are fundamentals we need to have in place. It's kind of fun to think about like in Chrome when you install an extension or like install an app, it's ask you like what permissions you're willing to give and be cool if in the future it says like, you can have access to my brain data. I mean, it's not unimaginable in the future that the big technology companies have built a business based upon acquiring data about you that they can then create a view to model of you and sell that predictability. And so it's not unimaginable that you will create with like kernel device, for example, a more reliable predictor of you than they could. And that they're asking you for permission to complete their objectives and you're the one that gets to negotiate that with them and say, sure. But so it's not unimaginable that might be the case. So there's a guy named Dela Musk and he has a company in one of the many companies called Neuralink that's also excited about the brain. So it'd be interesting to hear your kind of opinions about a very different approach that's invasive, that require surgery, that implants, a data collection device in the brain. How do you think about the difference between kernel and Neuralink in the approaches of getting that stream of brain data? Elon and I spoke about this a lot early on. We met up, I had started kernel and he had an interest in brain interfaces as well. And we explored doing something together, him joining kernel and ultimately it wasn't the right move. And so he started Neuralink and I continued building kernel, but it was interesting because we were both at this very early time where it wasn't certain if there was a path to pursue, if now was the right time to do something and then the technological choice of doing that. And so we were both, our starting point was looking at invasive technologies. And I was building invasive technology at the time. That's ultimately where he's gone. Little less than a year after Elon and I were engaged, I shifted kernel to do noninvasive. And we had this neuroscientist come to kernel. We were talking about, he had been doing neural surgery for 30 years, one of the most respected neuroscientists in the US. And we brought him to kernel to figure out the ins and outs of his profession. And at the very end of our three hour conversation, he said, you know, every 15 or so years, a new technology comes along that changes everything. He said, it's probably already here. You just can't see it yet. And my jaw dropped. I thought, because I had spoken to Bob Greenberg who had built a second site first on the optical nerve and then he did an array on the optical cortex. And then I also became friendly with Neuropace who does the implants for seizure detection and remediation. And I saw in their eyes what it was like to take something through an implantable device through for a 15 year run. They initially thought it was seven years and ended up being 15 years. And they thought it'd be a hundred million because it was 300, 400 million. And I really didn't want to build invasive technology. It was the only thing that appeared to be possible. But then once I spun up an internal effort to start looking at noninvasive options, we said, is there something here? Is there anything here that again has the characteristics of it has the high quality data, it could be low cost, it could be accessible. Could it make brain interfaces mainstream? And so I did a bet the company move. We shifted from noninvasive to invasive to noninvasive. So the answer is yes to that. There is something there that's possible. The answer is we'll see. We've now built both technologies and they're now you experienced one of them today. We were applying, we're now deploying it. So we're trying to figure out what value is really there. But I'd say it's really too early to express confidence. Whether it's too, I think it's too early to assess which technological choice is the right one on what time scales. Yeah, time scales are really important here. Very important because if you look at the, like on the invasive side, there's so much activity going on right now of less invasive techniques to get at the neuron firings, which would what Neuralink is building. It's possible that in 10, 15 years when they're scaling that technology, other things have come along. And you'd much rather do that. That thing starts to clock again. It may not be the case. It may be the case that Neuralink has properly chosen the right technology and that that's exactly what they want to be. Totally possible. And it's also possible that the path we chose that are noninvasive fall short for a variety of reasons. It's just, it's unknown. And so right now the two technologies we chose, the analogy I'd give you to create a baseline of understanding is if you think of it like the internet in the nineties, the internet became useful when people could do a dial up connection. And then as bandwidth increased, so did the utility of that connection and so did the ecosystem improve. And so if you say what kernel flow is going to give you a full screen on the picture of information, but as you're gonna be watching a movie, but the image is going to be blurred and the audio is gonna be muffled. So it has a lower resolution of coverage. A kernel flux, our MEG technology is gonna give you the full movie and 1080p. And Neuralink is gonna give you a circle on the screen of 4K. And so each one has their pros and cons and it's give and take. And so the decision I made with kernel was that these two technologies, flux and flow were basically the answer for the next seven years. And that they would give rise to the ecosystem which would become much more valuable than the hardware itself. And that we would just continue to improve on the hardware over time. And you know, it's early days, so. It's kind of fascinating to think about that. You don't, it's very true that you don't know both paths are very promising. And it's like 50 years from now we will look back and maybe not even remember one of them. And the other one might change the world. It's so cool how technology is. I mean, that's what entrepreneurship is, is like, it's the zero principle. It's like you're marching ahead into the darkness, into the fog, not knowing. It's wonderful to have someone else out there with us doing this. Because if you look at brain interfaces, anything that's off the shelf right now is inadequate. It's had its run for a couple of decades. It's still in hacker communities. It hasn't gone to the mainstream. The room size machines are on their own path. But there is no answer right now of bringing brain interfaces mainstream. And so it both, you know, both they and us, we've both spent over a hundred million dollars. And that's kind of what it takes to have a go at this. Cause you need to build full stack. I mean, at Kernel, we are from the photon and the atom through the machine learning. We have just under a hundred people. I think it's something like 36, 37 PhDs in these specialties, in these areas that there's only a few people in the world who have these abilities. And that's what it takes to build next generation, to make an attempt at breaking into brain interfaces. And so we'll see over the next couple of years, whether it's the right time or whether we were both too early or whether something else comes along in seven to 10 years, which is the right thing that brings it mainstream. So you see Elon as a kind of competitor or a fellow traveler along the path of uncertainty or both? It's a fellow traveler. It's like at the beginning of the internet is how many companies are going to be invited to this new ecosystem? Like an endless number. Because if you think that the hardware just starts the process. And so, okay, back to your initial example, if you take the Fitbit, for example, you say, okay, now I can get measurements on the body. And what do we think the ultimate value of this device is going to be? What is the information transfer rate? And they were in the market for a certain duration of time and Google bought them for two and a half billion dollars. They didn't have ancillary value add. There weren't people building on top of the Fitbit device. They also didn't have increased insight with additional data streams. So it was really just the device. If you look, for example, at Apple and the device they sell, you have value in the device that someone buys, but also you have everyone who's building on top of it. So you have this additional ecosystem value and then you have additional data streams that come in which increase the value of the product. And so if you say, if you look at the hardware as the instigator of value creation, over time what we've built may constitute five or 10% of the value of the overall ecosystem. And that's what we really care about. What we're trying to do is kickstart the mainstream adoption of quantifying the brain. And the hardware just opens the door to say what kind of ecosystem could exist. And that's why the examples are so relevant of the things you've outlined in your life. I hope those things, the books people write, the experiences people build, the conversations you have, your relationship with your AI systems, I hope those all are feeding on the insights built upon this ecosystem we've created to better your life. And so that's the thinking behind it. Again, with the Drake equation being the underlying driver of value. And the people at Kernel have joined not because we have certainty of success, but because we find it to be the most exhilarating opportunity we could ever pursue in this time to be alive. You founded the payment system Braintree in 2007 that acquired Venmo in 2012, in that same year was acquired by PayPal, which is now eBay. Can you tell me the story of the vision and the challenge of building an online payment system and just building a large successful business in general? I discovered payments by accident. When I was 21, I just returned from Ecuador living among extreme poverty for two years. And I came back to the US and I was shocked by the opulence of the United States of America. Yeah, of the United States. And I just thought this is, I couldn't believe it. And I decided I wanted to try to spend my life helping others. Like that was the, that was a life objective that I thought was worthwhile to pursue versus making money and whatever the case may be for its own right. And so I decided in that moment that I was going to try to make enough money by the age of 30 to never have to work again. And then with some abundance of money, I could then choose to do things that might be beneficial to others, but may not meet the criteria of being a standalone business. And so in that process, I started a few companies, had some small successes, had some failures. In one of the endeavors, I was up to my eyeballs in debt. Things were not going well. And I needed a part time job to pay my bills. And so I, one day I saw in the paper in Utah where I was living the 50 richest people in Utah. And I emailed each one of their assistants and said, you know, I'm young, I'm resourceful, I'll do anything. I'll just want to, I'm entrepreneurial. I tried to get a job that would be flexible and no one responded. And then I interviewed at a few dozen places. Nobody would even give me the time of day. Like it wouldn't want to take me seriously. And so finally I, it was on monster.com that I saw this job posting for credit card sales door to door. Commission. I did not know the story, this is great. I love the head drop, that's exactly right. So it was. The low points to which we go in life. So I responded and you know, the person made an attempt at suggesting that they had some kind of standards that they would consider hiring. But it's kind of like, if you could fog a mirror, like come and do this because it's 100% commission. And so I started walking up and down the street in my community selling credit card processing. And so what you learn immediately in doing that is if you walk into a business, first of all, the business owner is typically there. And you walk in the door and they can tell by how you're dressed or how you walk, whatever their pattern recognition is. And they just hate you immediately. It's like, stop wasting my time. I really am trying to get stuff done. I don't want us to a sales pitch. And so you have to overcome the initial get out. And then once you engage, when you say the word credit card processing, the person's like, I already hate you because I have been taken advantage of dozens of times because you all are weasels. And so I had to figure out an algorithm to get past all those different conditions. Cause I was still working on my other startup for the majority of my time. So I was doing this part time. And so I figured out that the industry really was built on people, on deceit, basically people promising things that were not reality. And so I don't know if you've heard of it, but we're not reality and so I'd walk into a business. I'd say, look, I would give you a hundred dollars. I'd put a hundred dollar bill and say, I'll give you a hundred dollars for three minutes of your time. If you don't say yes to what I'm saying, I'll give you a hundred dollars. And then he usually crack a smile and say, okay, like what do you got for me son? And so I'd sit down, I just opened my book and I'd say, here's the credit card industry. Here's how it works. Here are the players. Here's what they do. Here's how they deceive you. Here's what I am. I'm no different than anyone else. I it's like, you're gonna process your credit card. You're gonna get the money in the account. You're just gonna get a clean statement, you're gonna have someone who answers the call when someone asks and you know, just like the basic, like you're okay. And people started saying yes. And then of course I went to the next business and be like, you know, Joe and Susie and whoever said yes too. And so I built a social proof structure and I became the number one salesperson out of 400 people nationwide doing this. And I worked, you know, half time still doing this other startup and. That's a brilliant strategy, by the way. It's very well, very well strategized and executed. I did it for nine months. And at the time my customer base was making, was generating around, I think it was six, if I remember correctly, $62,504 a month were the overall revenues. I thought, wow, that's amazing. If I built that as my own company, I would just make $62,000 a month of income passively with these merchants processing credit cards. So I thought, hmm. And so that's when I thought I'm gonna create a company. And so then I started Braintree. And the idea was the online world was broken because PayPal had been acquired by eBay around, I think, 1999 or 2000. And eBay had not innovated much with PayPal. So it basically sat still for seven years as the software world moved along. And then authorize.net was also a company that was relatively stagnant. So you basically had software engineers who wanted modern payment tools, but there were none available for them. And so they just dealt with software they didn't like. And so with Braintree, I thought the entry point is to build software that engineers will love. And if we can find the entry point via software and make it easy and beautiful and just a magical experience and then provide customer service on top of that, that would be easy, that would be great. What I was really going after though, it was PayPal. They were the only company in payments making money. Because they had the relationship with eBay early on, people created a PayPal account, they'd fund their account with their checking account versus their credit cards. And then when they'd use PayPal to pay a merchant, PayPal had a cost of payment of zero versus if you have coming from a credit card, you have to pay the bank the fees. So PayPal's margins were 3% on a transaction versus a typical payments company, which may be a nickel or a penny or a dime or something like that. And so I knew PayPal really was the model to replicate, but a bunch of companies had tried to do that. They tried to come in and build a two sided marketplace. So get consumers to fund the checking account and the merchants to accept it, but they'd all failed because building a two sided marketplace is very hard at the same time. So my plan was I'm going to build a company and get the best merchants in the whole world to use our service. Then in year five, I'm going to have, I'm going to acquire a consumer payments company and I'm going to bring the two together. And to focus on the merchant side and then get the payments company that does the customer, the whatever, the other side of it. This is the plan I presented when I was at University of Chicago. And weirdly it happened exactly like that. So four years in our customer base included Uber, Airbnb, GitHub, 37 Signals, not Basecamp. We had a fantastic collection of companies that represented the fastest growing, some of the fastest growing tech companies in the world. And then we met up with Venmo and they had done a remarkable job in building product. It does up then something very counterintuitive, which is make public your private financial transactions which people previously thought were something that should be hidden from others. And we acquired Venmo and at that point we now had, we replicated the model because now people could fund their Venmo account with their checking account, keep money in the account. And then you could just plug Venmo as a form of payment. And so I think PayPal saw that, that we were getting the best merchants in the world. We had people using Venmo. They were both the up and coming millennials at the time who had so much influence online. And so they came in and offered us an attractive number. And my goal was not to build the biggest payments company in the world. It wasn't to try to climb the Forbes billionaire list. It was, the objective was I want to earn enough money so that I can basically dedicate my attention to doing something that could potentially be useful on a society wide scale. And more importantly, that could be considered to be valuable from the vantage point of 2050, 2100 and 2500. So thinking about it on a few hundred year timescale. And there was a certain amount of money I needed to do that. So I didn't require the permission of anybody to do that. And so that what PayPal offered was sufficient for me to get that amount of money to basically have a go. And that's when I set off to survey everything I could identify an existence to say of anything in the entire world I could do. What one thing could I do that would actually have the highest value potential for the species? And so it took me a little while to arrive at Brainerd Faces, but. Payments in themselves are revolutionary technologies that can change the world. Like let's not forget that too easily. I mean, obviously you know this, but there's quite a few lovely folks who are now fascinated with the space of cryptocurrency. And payments are very much connected to this, but in general, just money. And many of the folks I've spoken with, they also kind of connect that to not just purely financial discussions, but philosophical and political discussions. And they see Bitcoin as a way, almost as activism, almost as a way to resist the corruption of centralized centers of power. And sort of basically in the 21st century, decentralizing control. Whether that's Bitcoin or other cryptocurrencies, they see that's one possible way to give power to those that live in regimes that are corrupt or are not respectful of human rights and all those kinds of things. What's your sense, just all your expertise with payments and seeing how that changed the world, what's your sense about the lay of the land for the future of Bitcoin or other cryptocurrencies in the positive impact it may have on the world? To be clear, my communication wasn't meant to minimize payments or to denigrate it in any way. It was an attempt at communication that when I was surveying the world, it was an algorithm of what could I individually do? So there are things that exist that have a lot of potential that can be done. And then there's a filtering of how many people are qualified to do this given thing. And then there's a further characterization that can be done of, okay, given the number of qualified people, will somebody be a unique out performer of that group to make something truly impossible to be something done that otherwise couldn't get done? So there's a process of assessing where can you add unique value in the world? And some of that has to do with you being very formal and calculative here, but some of that is just like, what do you sense, like part of that equation is how much passion you sense within yourself to be able to drive that through, to discover the impossibilities and make them possible. That's right, and so we were at Braintree, I think we were the first company to integrate Coinbase into our, I think we were the first payments company to formally incorporate crypto, if I'm not mistaken. For people who are not familiar, Coinbase is a place where you can trade cryptocurrencies. Yeah, which was one of the only places you could. So we were early in doing that. And of course, this was in the year 2013. So an attorney to go in cryptocurrency land. I concur with the statement you made of the potential of the principles underlying cryptocurrencies. And that many of the things that they're building in the name of money and of moving value is equally applicable to the brain and equally applicable to how the brain interacts with the rest of the world and how we would imagine doing goal alignment with people. So to me, it's a continuous spectrum of possibility. And your question is isolated on the money. And I think it just is basically a scaffolding layer for all of society. So you don't see this money as particularly distinct from other? I don't. I think we at Kernel, we will benefit greatly from the progress being made in cryptocurrency because it will be a similar technology stack we will want to use for many things we want to accomplish. And so I'm bullish on what's going on and think it could greatly enhance brain interfaces and the value of the brain interface ecosystem. I mean, is there something you could say about, first of all, bullish on cryptocurrency versus fiat money? So do you have a sense that in 21st century cryptocurrency will be embraced by governments and changed the face of governments, the structure of governments? It's the same way I think about my diet, where previously it was conscious Brian, looking at foods in certain biochemical states. Am I hungry? Am I irritated? Am I depressed? And then I choose based upon those momentary windows. Do I eat at night when I'm fatigued and I have low willpower? Am I going to pig out on something? And the current monetary system is based upon human conscious decision making. And politics and power and this whole mess of things. And what I like about the building blocks of cryptocurrencies, it's methodical, it's structured, it is accountable, it's transparent. And so it introduces this scaffolding, which I think, again, is the right starting point for how we think about building next generation institutions for society. And that's why I think it's much broader than money. So I guess what you're saying is Bitcoin is the demotion of the conscious mind as well. In the same way you were talking about diet, it's like giving less priority to the ups and downs of any one particular human mind, in this case your own, and giving more power to the sort of data driven. Yes, yeah, I think that is accurate, that cryptocurrency is a version of what I would call my autonomous self that I'm trying to build. It is an introduction of an autonomous system of value exchange and the process of value creation in the society, yes, I see their similarities. So I guess what you're saying is Bitcoin will somehow help me not pig out at night, or the equivalent of, speaking of diet, if we could just linger on that topic a little bit, we already talked about your blog post of I fired myself, I fired Brian, the evening Brian, who's too willing to, not making good decisions for the long term well being and happiness of the entirety of the organism. Basically you were like pigging out at night. But it's interesting, because I do the same, in fact I often eat one meal a day, and like I have been this week actually, especially when I travel, and it's funny that it never occurred to me to just basically look at the fact that I'm able to be much smarter about my eating decisions in the morning and the afternoon than I am at night. So if I eat one meal a day, why not eat that one meal a day in the morning? Like I'm not, it never occurred to me, this revolutionary act, until you've outlined that. So maybe, can you give some details, and this is just you, this is one person, Brian, arrives at a particular thing that they do, but it's fascinating to kind of look at this one particular case study, so what works for you, diet wise? What's your actual diet, what do you eat, how often do you eat? My current protocol is basically the result of thousands of experiments and decision making. So I do this every 90 days, I do the tests, I do the cycle throughs, then I measure again, and then I'm measuring all the time. And so what I, of course I'm optimizing for my biomarkers, I want perfect cholesterol and I want perfect blood glucose levels and perfect DNA methylation processes. I also want perfect sleep. And so for example, recently, the past two weeks, my resting heart rate has been at 42 when I sleep. And when my resting heart rate's at 42, my HRV is at its highest. And I wake up in the morning feeling more energized than any other configuration. And so I know from all these processes that eating at roughly 8.30 in the morning, right after I work out on an empty stomach, creates enough distance between that completed eating and bedtime where I have almost no digestion processes going on in my body, therefore my resting heart rate goes very low. And when my resting heart rate's very low, I sleep with high quality. And so basically I've been trying to optimize the entirety of what I eat to my sleep quality. And my sleep quality then of course feeds into my willpower so it creates this virtuous cycle. And so at 8.30 what I do is I eat what I call super veggie, which is, it's a pudding of 250 grams of broccoli, 150 grams of cauliflower, and a whole bunch of other vegetables that I eat what I call nutty pudding, which is. You make the pudding yourself? Like, what do you call it? Like a veggie mix, whatever thing, like a blender? Yeah, you can be made in a high speed blender. But basically I eat the same thing every day, veggie bowl as in the form of pudding, and then a bowl in the form of nuts. And then I have. Vegan. Vegan, yes. Vegan, so that's fat and that's like, that's fat and carbs and that's the protein and so on. Then I have a third dish. Does it taste good? I love it. I love it so much I dream about it. Yeah, that's awesome. This is a. And then I have a third dish which is, it changes every day. Today it was kale and spinach and sweet potato. And then I take about 20 supplements that hopefully make, constitute a perfect nutritional profile. So what I'm trying to do is create the perfect diet for my body every single day. Where sleep is part of the optimization. That's right. You're like, one of the things you're really tracking. I mean, can you, well, I have a million question, but 20 supplements, like what kind are like, would you say are essential? Cause I only take, I only take athletic greens.com slash. That's like the multivitamin essentially. That's like the lazy man, you know, like, like if you don't actually want to think about shit, that's what you take and then fish oil and that's it. That's all I take. Yeah, you know, Alfred North Whitehead said, civilization advances as it extends the number of important operations it can do without thinking about them. Yes. So my objective on this is I want an algorithm for perfect health that I never have to think about. And then I want that system to be scalable to anybody so that they don't have to think about it. And right now it's expensive for me to do it. It's time consuming for me to do it. And I have infrastructure to do it, but the future of being human is not going to the grocery store and deciding what to eat. It's also not reading scientific papers, trying to decide this thing or that thing. It's all N of one. So it's devices on the outside and inside your body, assessing real time what your body needs and then creating closed loop systems for that to happen. Yeah, so right now you're doing the data collection and you're being the scientist, it'd be much better if you just did the data collect or it was being essentially done for you and you can outsource that to another scientist that's doing the N of one study of you. That's right, because every time I spend time thinking about this or executing, spending time on it, I'm spending less time thinking about building kernel or the future of being human. And so it's, we just all have the budget of our capacity on an everyday basis and we will scaffold our way up out of this. And so, yeah, hopefully what I'm doing is really, it serves as a model that others can also build on. That's why I wrote about it, is hopefully people can then take it and improve upon it. I hold nothing sacred. I change my diet almost every day based upon some new test results or science or something like that, but. Can you maybe elaborate on the sleep thing? Why is sleep so important? And why, presumably, like what does good sleep mean to you? I think sleep is a contender for being the most powerful health intervention in existence. It's a contender. I mean, it's magical what it does if you're well rested and what your body can do. And I mean, for example, I know when I eat close to my bedtime and I've done a systematic study for years looking at like 15 minute increments on time of day on where I eat my last meal, my willpower is directly correlated to the amount of deep sleep I get. So my ability to not binge eat at night when rascal Brian's out and about is based upon how much deep sleep I got the night before. Yeah, there's a lot to that, yeah. And so I've seen it manifest itself. And so I think the way I summarize this is in society we've had this myth of, we tell stories, for example, of entrepreneurship where this person was so amazing, they stayed at the office for three days and slept under their desk. And we say, wow, that's amazing, that's amazing. And now I think we're headed towards a state where we'd say that's primitive and really not a good idea on every level. And so the new mythology is going to be the exact opposite. Yeah, by the way, just to sort of maybe push back a little bit on that idea. Did you sleep under your desk collects? Well, yeah, a lot. I'm a big believer in that actually. I'm a big believer in chaos and giving into your passion and sometimes doing things that are out of the ordinary that are not trying to optimize health for certain periods of time in lieu of your passions is a signal to yourself that you're throwing everything away. So I think what you're referring to is how to have good performance for prolonged periods of time. I think there's moments in life where you need to throw all of that away, all the plans away, all the structure away. So I'm not sure I have an eloquent way describing exactly what I'm talking about, but it all depends on people, people are different, but there's a danger of over optimization to where you don't just give into the madness of the way your brain flows. I mean, to push back on my pushback is like, it's nice to have like where the foundations of your brain are not messed with. So you have a fixed foundation where the diet is fixed, where the sleep is fixed and that all of that is optimal and the chaos happens in the space of ideas as opposed to the space of biology. But I'm not sure if there's a, that requires real discipline and forming habits. There's some aspect to which some of the best days and weeks of my life have been, yeah, sleeping under a desk kind of thing. And I don't, I'm not too willing to let go of things that empirically worked for things that work in theory. And so I'm, again, I'm absolutely with you on sleep. Also, I'm with you on sleep conceptually, but I'm also very humbled to understand that for different people, good sleep means different things. I'm very hesitant to trust science on sleep. I think you should also be a scholar of your own body. Again, the experiment of NF1. I'm not so sure that a full night's sleep is great for me. There is something about that power nap that I just have not fully studied yet, but that nap is something special. That I'm not sure I found the optimal thing. So like there's a lot to be explored to what is exactly optimal amount of sleep, that has the characteristics of, it has the data quality is high enough, it meets some certain threshold, cost, accessibility, comfort, it can be worn in contextual environments. If it meets the criteria of being a mass market device, then the responsibility that we have is to figure out how to create the algorithm that enables the human, to enable humans to then find value with it. So the analogy is like brain interfaces are like early 90s of the internet, is you wanna populate an ecosystem with a certain number of devices, you want a certain number of people who play around with them, who do experiments of certain data collection parameters, you want to encourage certain mistakes from experts and non experts. These are all critical elements that ignite discovery. And so we believe we've accomplished the first objective of building technology that reaches those thresholds. And now it's the Drake equation component of how do we try to generate 20 years of value discovery in a two or three year time period? How do we compress that? So just to clarify, so when you mean the Drake equation, which for people who don't know, I don't know why you, if you listen to this, I bring up aliens every single conversation. So I don't know how you would know what the Drake equation is, but you mean like the killer app, it would be one alien civilization in that equation. So meaning like this is in search of an application that's impactful, transformative. By the way, it should be, we need to come up with a better term than killer app as a. It's also violent, right? It's very violent. You can go like viral app, that's horrible too, right? It's some very inspiringly impactful application. How about that? No. Yeah. Okay, so ballistic with killer app, that's fine. Nobody's. But I concur with you. I dislike the chosen words in capturing the concept. You know, it's one of those sticky things that is as effective to use in the tech world. But when you now become a communicator outside of the tech world, especially when you're talking about software and hardware and artificial intelligence applications, it sounds horrible. Yeah, no, it's interesting. I actually regret now having called attention to cyber regret having used that word in this conversation because it's something I would not normally do. I used it in order to create a bridge of shared understanding of how others would, what terminology others would use. Yeah. But yeah, I concur. Let's go with impactful application. Or the. Just value creation. Value creation. Something people love using. There we go, that's it. Love app. Okay, so what, do you have any ideas? So you're basically creating a framework where there's the possibility of a discovery of an application that people love using. Is, do you have ideas? We've began to play a fun game internally where when we have these discussions or we begin circling around this concept of, does anybody have an idea? Does anyone have intuitions? And if we see the conversation starting to veer in that direction, we flag it and say, human intuition alert, stop it. And so we really want to focus on the algorithm of there's a natural process of human discovery. That when you populate a system with devices and you give people the opportunity to play around with it in expected and unexpected ways, we are thinking that is a much better system of discovery than us exercising intuitions. And it's interesting, we're also seeing a few neuroscientists who have been talking to us. While I was speaking to this one young associate professor, and I approached a conversation and said, hey, we have these five data streams that we're pulling off. When you hear that, what weighted value do you add to each data source? Which one do you think is going to be valuable for your objectives and which one's not? And he said, I don't care, just give me the data. All I care about is my machine learning model. But importantly, he did not have a theory of mind. He did not come to the table and say, I think the brain operates in this way and these reasons or have these functions. He didn't care, he just wanted the data. And we're seeing that more and more that certain people are devaluing human intuitions for good reasons, as we've seen in machine learning over the past couple years. And we're doing the same in our value creation market strategy. So collect more data, clean data, make the product such that the collection of data is easy and fun and then the rest will just spring to life. Through humans playing around with them. Our objective is to create the most valuable data collection system of the brain ever. And with that, then applying all the best tools of machine learning and other techniques to extract out, to try to find insight. But yes, our objective is really to systematize the discovery process because we can't put definite timeframes on discovery. The brain is complicated and science is not a business strategy. And so we really need to figure out how to, this is the difficulty of bringing technology like this to market. And it's why most of the time it just languishes in academia for quite some time. But we hope that we will cross over and make this mainstream in the coming years. The thing was cool to wear, but are you chasing a good reason for millions of people to put this on their head and keep on their head regularly? Is there, like who's going to discover that reason? Is it going to be people just kind of organically or is there going to be an Angry Birds style application that's just too exciting to not use? If I think through the things that have changed my life most significantly over the past few years, when I started wearing a wearable on my wrist that would give me data about my heart rate, heart rate variability, respiration rate, metabolic approximations, et cetera, for the first time in my life, I had access to information, sleep patterns that were highly impactful. They told me, for example, if I eat close to bedtime, I'm not going to get deep sleep. And not getting deep sleep means you have all these follow on consequences in life. And so it opened up this window of understanding of myself that I cannot self introspect and deduce these things. This is information that was available to be acquired, but it just wasn't. I would have to get an expensive sleep study, then it's an end, like one night, and that's not good enough to look at, to run all my trials. And so if you look just at the information that one can acquire on their wrist, and now you're applying it to the entire cortex on the brain and you say, what kind of information could we acquire? It opens up a whole new universe of possibilities. For example, we did this internal study at Kernel where I wore a prototype device and we were measuring the cognitive effects of sleep. So I had a device measuring my sleep. I performed with 13 of my coworkers. We performed four cognitive tasks over 13 sessions. And we focused on reaction time, impulse control, short term memory, and then a resting state task. And with mine, we found, for example, that my impulse control was independently correlated with my sleep outside of behavioral measures of my ability to play the game. The point of the study was I had, the brain study I did at Kernel confirmed my life experience that if I, my deep sleep determined whether or not I would be able to resist temptation the following day. And my brain did show that as one example. And so if you start thinking, if you actually have data on yourself, on your entire cortex and you can control the settings, I think there's probably a large number of things that we could discover about ourselves, very, very small and very, very big. I just, for example, like when you read news, what's going on? Like when you use social media, when you use news, like all the ways we allocate attention. That's right. With the computer. I mean, that seems like a compelling place to where you would want to put on a Kernel, by the way, what is it called? Kernel Flux, Kernel, like what? Flow. Flow. We have two technologies, you or Flow. Flow, okay. So when you put on the Kernel Flow, it seems like to be a compelling time and place to do it is when you're behind a desk, behind a computer. Because you could probably wear it for prolonged periods of time as you're taking in content. And there could a lot of, because so much of our lives happens in the digital world now. That kind of coupling the information about the human mind with the consumption and the behaviors in the digital world might give us a lot of information about the effects of the way we behave and navigate the digital world to the actual physical meat space effects on our body. It's interesting to think, so in terms of both like for work, I'm a big fan of Cal Newport, his ideas of deep work that I spend, with few exceptions, optimal kind of sleep combined with diet and all those kinds of things. I mean, that all maps the sort of data, at least the truth, exactly what you're referring to. Here's a data point for your consideration. Yes. The progress in biology over the past, say decade, has been stunning. Yes. And it now appears as if we will be able to replace our organs, zero X for a transplantation. And so we probably have a path to replace and regenerate every organ of your body, except for your brain. You can lose your hand and your arm and a leg. You can have an artificial heart. You can't operate without your brain. And so when you make that trade off decision of whether you're going to sleep under the desk or not and go all out for a four day marathon, right? There's a cost benefit trade off of what's going on, what's happening to your brain in that situation. We don't know the consequences of modern day life on our brain. We don't, it's the most valuable organ in our existence. And we don't know what's going on if we, in how we're treating it today with stress and with sleep and with dietary. And to me, then if you say that you're trying to, you're trying to optimize life for whatever things you're trying to do. The game is soon with the progress in anti aging and biology, the game is very soon going to become different than what it is right now with organ rejuvenation, organ replacement. And I would conjecture that we will value the health status of our brain above all things. Yeah, no, absolutely. Everything you're saying is true, but we die. We die pretty quickly, life is short. And I'm one of those people that I would rather die in battle than stay safe at home. It's like, yeah, you look at kind of, there's a lot of things that you can reasonably say, these are, this is the smart thing to do that can prevent you, that becomes conservative, that can prevent you from fully embracing life. I think ultimately you can be very intelligent and data driven and also embrace life. But I err on the side of embracing life. It's very, it takes a very skillful person to not sort of that hovering parent that says, you know what, there's a 3% chance that if you go out, if you go out by yourself and play, you're going to die, get run over by a car, come to a slow or a sudden end. And I am more a supporter of just go out there. If you die, you die. And that's a, it's a balance you have to strike. I think there's a balance to strike in the longterm optimization and short term freedom. For me, for a programmer, for a programming mind, I tend to over optimize and I'm very cautious and afraid of that, to not over optimize and thereby be overly cautious, suboptimally cautious about everything I do. And that's the ultimate thing I'm trying to optimize for. It's funny you said like sleep and all those kinds of things. I tend to think, this is, you're being more precise than I am, but I think I tend to want to minimize stress, which everything comes into that from your sleep and all those kinds of things. But I worry that whenever I'm trying to be too strict with myself, then the stress goes up when I don't follow the strictness. And so you have to kind of, it's a weird, it's a, there's so many variables in an objective function as it's hard to get right. And sort of not giving a damn about sleep and not giving a damn about diet is a good thing to inject in there every once in a while for somebody who's trying to optimize everything. But that's me just trying to, it's exactly like you said, you're just a scientist, I'm a scientist of myself, you're a scientist of yourself. It'd be nice if somebody else was doing it and had much better data, because I don't trust my conscious mind and I pigged out last night at some brisket in LA that I regret deeply. It's just so, uh. There's no point to anything I just said. But. But. What is the nature of your regret on the brisket? Is it, do you wish you hadn't eaten it entirely? Is it that you wish you hadn't eaten as much as you did? Is it that? I think, well, the most regret, I mean, if we want to be specific, I drank way too much like that. Like diet soda. My biggest regret is like having drank so much diet soda. That's the thing that really was the problem. I had trouble sleeping because of that. Because I was like programming and then I was editing. And so I'd stay up late at night and then I had to get up to go pee a few times and it was just a mess. A mess of a night. It was, well, it's not really a mess, but like it's so many, it's like the little things. I know if I just eat, I drink a little bit of water and that's it, and there's a certain, all of us have perfect days that we know diet wise and so on that's good to follow, you feel good. I know what it takes for me to do that. I didn't fully do that and thereby, because there's an avalanche effect where the other sources of stress, all the other to do items I have piled on, my failure to execute on some basic things that I know make me feel good and all of that combines to create a mess of a day. But some of that chaos, you have to be okay with it, but some of it I wish was a little bit more optimal. And your ideas about eating in the morning are quite interesting as an experiment to try. Can you elaborate, are you eating once a day? Yes. In the morning and that's it. Can you maybe speak to how that, you spoke, it's funny, you spoke about the metrics of sleep, but you're also, you run a business, you're incredibly intelligent, mostly your happiness and success relies on you thinking clearly. So how does that affect your mind and your body in terms of performance? So not just sleep, but actual mental performance. As you were explaining your objective function of, for example, in the criteria you were including, you like certain neurochemical states, like you like feeling like you're living life, that life has enjoyment, that sometimes you want to disregard certain rules to have a moment of passion, of focus. There's this architecture of the way Lex is, which makes you happy as a story you tell, as something you kind of experience, maybe the experience is a bit more complicated, but it's in this idea you have, this is a version of you. And the reason why I maintain the schedule I do is I've chosen a game to say, I would like to live a life where I care more about what intelligent, what people who live in the year 2500 think of me than I do today. That's the game I'm trying to play. And so therefore the only thing I really care about on this optimization is trying to see past myself, past my limitations, using zeroes principle thinking, pull myself out of this contextual mesh we're in right now and say, what will matter 100 years from now and 200 years from now? What are the big things really going on that are defining reality? And I find that if I were to hang out with Diet Soda Lex and Diet Soda Brian were to play along with that and my deep sleep were to get crushed as a result, my mind would not be on what matters in 100 years or 200 years or 300 years. I would be irritable. I would be, I'd be in a different state. And so it's just gameplay selection. It's what you and I have chosen to think about. It's what we've chosen to work on. And this is why I'm saying that no generation of humans have ever been afforded the opportunity to look at their lifespan and contemplate that they will have the possibility of experiencing an evolved form of consciousness that is undeniable. They would fall in a zero category of potential. That to me is the most exciting thing in existence. And I would not trade any momentary neurochemical state right now in exchange for that. I would, I'd be willing to deprive myself of all momentary joy in pursuit of that goal because that's what makes me happy. That's brilliant. But I'm a bit, I just looked it up. I'm with, I just looked up Braveheart's speech and William Wallace, but I don't know if you've seen it. Fight and you may die, run and you'll live at least a while. And dying in your beds many years from now, would you be willing to trade all the days from this day to that for one chance, just one chance, picture Mel Gibson saying this, to come back here and tell our enemies that they may take our lives with growing excitement, but they'll never take our freedom. I get excited every time I see that in the movie, but that's kind of how I approach life and eating. Do you think they were tracking their sleep? They were not tracking their sleep and they ate way too much brisket and they were fat, unhealthy, died early, and were primitive. But there's something in my ape brain that's attracted to that, even though most of my life is fully aligned with the way you see yours. Part of it is for comedy, of course, but part of it is I'm almost afraid of overoptimization. Really what you're saying though, if we're looking at this, let's say from a first principles perspective, when you read those words, they conjure up certain life experiences, but you're basically saying, I experienced a certain neurotransmitter state when these things are in action. That's all you're saying. So whether it's that or something else, you're just saying you have a selection for how your state for your body. And so if you as an engineer of consciousness, that should just be engineerable. And that's just triggering certain chemical reactions. And so it doesn't mean they have to be mutually exclusive. You can have that and experience that and also not sacrifice longterm health. And I think that's the potential of where we're going is we don't have to assume they are trade offs that must be had. Absolutely. And so I guess for my particular brain, it's useful to have the outlier experiences that also come along with the illusion of free will where I chose those experiences that make me feel like it's freedom. Listen, going to Texas made me realize I spent, so I still am, but I lived at Cambridge at MIT and I never felt like home there. I felt like home in the space of ideas with the colleagues, like when I was actually discussing ideas, but there is something about the constraints, how cautious people are, how much they valued also kind of a material success, career success. When I showed up to Texas, it felt like I belong. That was very interesting, but that's my neurochemistry, whatever the hell that is, whatever, maybe probably is rooted to the fact that I grew up in the Soviet Union and it was such a constrained system that you'd really deeply value freedom and you always want to escape the man and the control of centralized systems. I don't know what it is, but at the same time, I love strictness. I love the dogmatic authoritarianism of diet, of like the same habit, exactly the habit you have. I think that's actually when bodies perform optimally, my body performs optimally. So balancing those two, I think if I have the data, every once in a while, party with some wild people, but most of the time eat once a day, perhaps in the morning, I'm gonna try that. That might be very interesting, but I'd rather not try it. I'd rather have the data that tells me to do it. But in general, you're able to, eating once a day, think deeply about stuff like this. Concern that people have is like does your energy wane, all those kinds of things. Do you find that it's, especially because it's unique, it's vegan as well. So you find that you're able to have a clear mind, a focus, and just physically and mentally throughout? Yeah, and I find like my personal experience in thinking about hard things is, like oftentimes I feel like I'm looking through a telescope and like I'm aligning two or three telescopes. And you kind of have to close one eye and move it back and forth a little bit and just find just the right alignment. Then you find just a sneak peek at the thing you're trying to find, but it's fleeting. If you move just one little bit, it's gone. And oftentimes what I feel like are the ideas I value the most are like that. They're so fragile and fleeting and slippery and elusive. And it requires a sensitivity to thinking and a sensitivity to maneuver through these things. If I concede to a world where I'm on my phone texting, I'm also on social media. I'm also doing 15 things at the same time because I'm running a company and I'm also feeling terrible from the last night. It all just comes crashing down. And the quality of my thoughts goes to a zero. I'm a functional person to respond to basic level things, but I don't feel like I am doing anything interesting. I think that's a good word, sensitivity, because that's the word that's used the most. That's what thinking deeply feels like is you're sensitive to the fragile thoughts. And you're right. All those other distractions kind of dull your ability to be sensitive to the fragile thoughts. It's a really good word. Out of all the things you've done, you've also climbed Mount Kilimanjaro. Is this true? It's true. Why and how, and what do you take from that experience? I guess the backstory is relevant because in that moment, it was the darkest time in my life. I was ending a 13 year marriage. I was leaving my religion. I sold Braintree and I was battling depression where I was just at the end. And I got invited to go to Tanzania as part of a group that was raising money to build clean water wells. And I had made some money from Braintree, and so I was able to donate $25,000. And it was the first time I had ever had money to donate outside of paying tithing in my religion. It was such a phenomenal experience to contribute something meaningful to someone else in that form. And as part of this process, we were gonna climb the mountain. And so we went there and we saw the clean water wells we were building. We spoke to the people there and it was very energizing. And then we climbed Kilimanjaro and I came down with a stomach flu on day three. And I also had altitude sickness, but I became so sick that on day four, we are somebody on day five, I came into the camp, base camp at 15,000 feet, just going to the bathroom on myself and falling all over. I was just a disaster, I was so sick. So stomach flu and altitude sickness. Yeah, and I just was destroyed from the situation. Plus, it was psychologically one of the lowest points. Yeah, and I think that was probably a big contributor. I was just smoked as a human, just absolutely done. And I had three young children. And so I was trying to reconcile, this is not a, whether I live or not is not my decision by itself. I'm now intertwined with these three little people and I have an obligation whether I like it or not, I need to be there. And so it did, it felt like I was just stuck in a straight jacket. And I had to decide whether I was going to summit the next day with the team. And it was a difficult decision because once you start hiking, there's no way to get off the mountain. And a midnight came and our guide came in and he said, where are you at? And I said, I think I'm okay, I think I can try. And so we went. And so from midnight to, I made it to the summit at 5 a.m. It was one of the most transformational moments of my existence. And the mountain became my problem. It became everything that I was struggling with. And when I started hiking, it was, the pain got so ferocious that it was kind of like this. It became so ferocious that I turned my music to Eminem and it was, Eminem was the, he was the only person in existence that spoke to my soul. And it was something about his anger and his vibrancy and his multi eventually, he's the only person who I could turn on and I could just say, I feel some relief. I turned on Eminem and I made it to the summit after five hours, but just 100 yards from the top. I was with my guide Ike and I started getting very dizzy and I felt like I was gonna fall backwards off this cliff area we were on. I was like, this is dangerous. And he said, look, Brian, I know where you're at. I know where you're at. And I can tell you, you've got it in you. So I want you to look up, take a step, take a breath and look up, take a breath and take a step. And I did and I made it. And so I got there and I just sat down with him at the top. I just cried like a baby. Broke down. Yeah, I just lost it. And so he'd let me do my thing. And then we pulled out the pulse oximeter and he measured my blood oxygen levels and it was like 50 something percent and it was danger zone. So he looked at it and I think he was like really alarmed that I was in this situation. And so he said, we can't get a helicopter here and we can't get you emergency evacuated. You've gotta go down. You've gotta hike down to 15,000 feet to get base camp. And so we went out on the mountain. I got back down to base camp. And again, that was pretty difficult. And then they put me on a stretcher, this metal stretcher with this one wheel and a team of six people wheeled me down the mountain. And it was pretty torturous. I'm very appreciative they did. Also the trail was very bumpy. So they'd go over the big rocks. And so my head would just slam against this metal thing for hours. And so I just felt awful. Plus I'd get my head slammed every couple of seconds. So the whole experience was really a life changing moment. And that was the demarcation of me basically building a new life. Basically I said, I'm going to reconstruct Brian, my understanding of reality, my existential realities, what I want to go after. And I try, I mean, as much as that's possible as a human, but that's when I set out to rebuild everything. Was it the struggle of that? I mean, there's also just like the romantic poetic, it's a fricking mountain. There's a man in pain, psychological and physical struggling up a mountain. But it's just struggle, just in the face of, just pushing through in the face of hardship or nature too. Something much bigger than you. Is that, was that the thing that just clicked? For me, it felt like I was just locked in with reality and it was a death match. It was in that moment, one of us is going to die. So you were pondering death, like not surviving. Yep. And it was, and that was the moment. And it was, the summit to me was, I'm going to come out on top and I can do this. And giving in was, it's like, I'm just done. And so it did, I locked in and that's why, yeah, mountains are magical to me. I didn't expect that. I didn't design that. I didn't know that was going to be the case. I not, it would not have been something I would have anticipated. But you were not the same man afterwards. Yeah. Is there advice you can give to young people today that look at your story, that's successful in many dimensions, advice you can give to them about how to be successful in their career, successful in life, whatever path they choose? Yes, I would say, listen to advice and see it for what it is, a mirror of that person, and then map and know that your future is going to be in a zero principle land. And so what you're hearing today is a representation of what may have been the right principles to build upon previously, but they're likely depreciating very fast. And so I am a strong proponent that people ask for advice, but they don't take advice. So how do you take advice properly? It's in the careful examination of the advice. It's actually the person makes a statement about a given thing somebody should follow. The value is not doing that. The value is understanding the assumption stack they built, the assumption and knowledge stack they built around that body of knowledge. That's the value. It's not doing what they say. Considering the advice, but digging deeper to understand the assumption stack, like the full person, I mean, this is deep empathy, essentially, to understand the journey of the person that arrived at the advice. And the advice is just the tip of the iceberg that ultimately is not the thing that gives you. It could be the right thing to do. It could be the complete wrong thing to do depending on the assumption stack. So you need to investigate the whole thing. Is there some, are there been people in your startup and your business journey that have served that role of advice giver that's been helpful? Or do you feel like your journey felt like a lonely path? Or was it one that was, of course, we're all there born and die alone. But do you fundamentally remember the experiences, one where you leaned on people at a particular moment in time that changed everything? Yeah, the most significant moments of my memory, for example, like on Kilimanjaro, when Ike, some person I'd never met in Tanzania, was able to, in that moment, apparently see my soul when I was in this death match with reality. And he gave me the instructions, look up, step. And so there's magical people in my life that have done things like that. And I suspect they probably don't know. I probably should be better at identifying those things. And, but yeah, hopefully the, I suppose like the wisdom I would aspire to is to have the awareness and the empathy to be that for other people. And not a retail advertiser of advice, of tricks for life, but deeply meaningful and empathetic with a one on one context with people that it really can make a difference. Yeah, I actually kind of experience, I think about that sometimes. You have like an 18 year old kid come up to you. And it's not always obvious, it's not always easy to really listen to them. Like not the facts, but like see who that person is. I think people say that about being a parent is you want to consider that, you don't want to be the authority figure in the sense that you really want to consider that there's a special unique human being there with a unique brain that may be brilliant in ways that you are not understanding that you'll never be and really try to hear that. So when giving advice, there's something to that. It's a both sides should be deeply empathetic about the assumption stack. I love that terminology. What do you think is the meaning of this whole thing of life? Why the hell are we here, Brian Johnson? We've been talking about brains and studying brains and you had this very eloquent way of describing life on Earth as an optimization problem of the cost of intelligence going to zero. At first through the evolutionary process and then eventually through building, through our technology, building more and more intelligent systems. You ever ask yourself why is doing that? Yeah, I think the answer to this question, again, the information value is more in the mirror it provides of that person, which is a representation of the technological, social, political context of the time. So if you ask this question a hundred years ago, you would get a certain answer that reflects that time period. Same thing would be true of a thousand years ago. It's rare, it's difficult for a person to pull themselves out of their contextual awareness and offer a truly original response. And so knowing that I am contextually influenced by the situation, that I am a mirror for our reality, I would say that in this moment, I think the real game going on is that evolution built a system of scaffolding intelligence that produced us. We are now building intelligence systems that are scaffolding higher dimensional intelligence, that's developing more robust systems of intelligence. In doing in that process with the cost going to zero, then the meaning of life becomes goal alignment, which is the negotiation of our conscious and unconscious existence. And then I'd say the third thing is, if we're thinking that we wanna be explorers is our technological progress is getting to a point where we could aspirationally say, we want to figure out what is really going on, really going on, because does any of this really make sense? Now we may be a hundred, 200, 500, a thousand years away from being able to poke our way out of whatever is going on. But it's interesting that we could even state an aspiration to say, we wanna poke at this question. But I'd say in this moment of time, the meaning of life is that we can build a future state of existence that is more fantastic than anything we could ever imagine. The striving for something more amazing. And that defies expectations that we would consider bewildering and all the things that that's, and I guess the last thing, if there's multiple meanings of life, it would be infinite games. James Kars wrote the book, Finite Games, Infinite Games. The only game to play right now is to keep playing the game. And so this goes back to the algorithm of the Lex algorithm of diet soda and brisket and pursuing the passion. What I'm suggesting is there's a moment here where we can contemplate playing infinite games. Therefore, it may make sense to err on the side of making sure one is in a situation to be playing infinite games if that opportunity arises. So the landscape of possibility is changing very, very fast and therefore our old algorithms of how we might assess risk assessment and what things we might pursue and why those assumptions may fall away very quickly. Well, I think I speak for a lot of people when I say that the game you, Mr. Brian Johnson, have been playing is quite incredible. Thank you so much for talking to me. Thanks, Lex. Thanks for listening to this conversation with Brian Johnson and thank you to Four Sigmatic, NetSuite, Grammarly, and ExpressVPN. Check them out in the description to support this podcast. And now let me leave you with some words from Diane Ackerman. Our brain is a crowded chemistry lab, bustling with nonstop neural conversations. Thank you for listening and hope to see you next time. I try to spend the first two hours of every day, usually if I'm like at home and have nothing on my schedule is going to be up to eight hours of deep work, of focus, zero distraction. And for me to analyze, I mean I'm very aware of the waning of that, the ups and downs of that. And it's almost like you're surfing the ups and downs of that as you're doing programming, as you're doing thinking about particular problems, you're trying to visualize things in your mind, you start trying to stitch them together. You're trying to, when there's a dead end about an idea, you have to kind of calmly like walk back and start again, all those kinds of processes. It'd be interesting to get data on what my mind is actually doing. And also recently started doing, I just talked to Sam Harris a few days ago and been building up to that. I started using, started meditating using his app, Waking Up, I very much recommend it. It'd be interesting to get data on that because it's, you're very, it's like you're removing all the noise from your head and you very much, it's an active process of active noise removal, active noise canceling like the headphones. And it'd be interesting to see what is going on in the mind before the meditation, during it and after, all those kinds of things. And all of your examples, it's interesting that everyone who's designed an experience for you, so whether it be the meditation app or the Deep Work or all the things you mentioned, they constructed this product with a certain number of knowns. Yeah. Now, what if we expanded the number of knowns by 10X or 20X or 30X, they would reconstruct their product or incorporate those knowns. So it'd be, and so this is the dimensionality that I think is the promising aspect is that people will be able to use this quantification, use this information to build more effective products. And this is, I'm not talking about better products to advertise to you or manipulate you. I'm talking about our focus is helping people, individuals have this contextual awareness and this quantification and then to engage with others who are seeking to improve people's lives, that the objective is betterment across ourselves, individually and also with each other. Yeah, so it's a nice data stream to have if you're building an app, like if you're building a podcast listening app, it would be nice to know data about the listener so that like if you're bored or you fell asleep, maybe pause the podcast, it's like really dumb, just very simple applications that could just improve the quality of the experience of using the app. I'm imagining if you have your neural, this is Lex and there's a statistical representation of you and you engage with the app and it says, Lex, you're best to engage with this meditation exercise in the following settings. At this time of day, after eating this kind of food or not eating, fasting with this level of blood glucose and this kind of night's sleep. But all these data combined to give you this contextually relevant experience, just like we do with our sleep. You've optimized your entire life based upon what information you can acquire and know about yourself. And so the question is, how much do we really know of the things going around us? And I would venture to guess in my own life experience, I capture, my self awareness captures an extremely small percent of the things that actually influence my conscious and unconscious experience. Well, in some sense, the data would help encourage you to be more self aware, not just because you trust everything the data is saying, but it'll give you a prod to start investigating. Like I would love to get like a rating, like a ranking of all the things I do and what are the things, it's probably important to do without the data, but the data will certainly help. It's like rank all the things you do in life and which ones make you feel shitty, which ones make you feel good. Like you're talking about evening, Brian. Like this is a good example, somebody like, I do pig out at night as well. And it never makes me feel good. Like you're in a safe space. This is a safe space, let's hear it. No, I definitely have much less self control at night and it's interesting. And the same, people might criticize this, but I know my own body. I know when I eat carnivores, just eat meat, I feel much better than if I eat more carbs. The more carbs I eat, the worse I feel. I don't know why that is. There is science supporting it, but I'm not leaning on science. I'm leaning on personal experience and that's really important. I don't need to read, I'm not gonna go on a whole rant about nutrition science, but many of those studies are very flawed. They're doing their best, but nutrition science is a very difficult field of study because humans are so different and the mind has so much impact on the way your body behaves. And it's so difficult from a scientific perspective to conduct really strong studies that you have to be almost like a scientist of one if to do these studies on yourself. That's the best way to understand what works for you or not. And I don't understand why, because it sounds unhealthy, but eating only meat always makes me feel good. Just eat meat, that's it. And I don't have any allergies, any of that kind of stuff. I'm not full like Jordan Peterson, where if he deviates a little bit from the carnivore diet, he goes off the cliff. No, I can have chocolate, I can go off the diet, I feel fine, it's a gradual worsening of how I feel. But when I eat only meat, I feel great. And it'd be nice to be reminded of that. Like there's a very simple fact that I feel good when I eat carnivore. And I think that repeats itself in all kinds of experiences. Like I feel really good when I exercise. I hate exercise, but in the rest of the day, the impact it has on my mind and the clarity of mind and the experiences and the happiness and all those kinds of things, I feel really good. And to be able to concretely express that through data would be nice. It would be a nice reminder, almost like a statement, like remember what feels good and whatnot. And there could be things like that, I'm not, many things that you're suggesting that I could not be aware of, that might be sitting right in front of me that make me feel really good and make me feel not good. And the data would show that. I agree with you. I've actually employed the same strategy. I fired my mind entirely from being responsible for constructing my diet. And so I started doing a program where I now track over 200 biomarkers every 90 days. And it captures, of course, the things you would expect like cholesterol, but also DNA methylation and all kinds of things about my body, all the processes that make up me. And then I let that data generate the shopping lists. And so I never actually ask my mind what it wants. It's entirely what my body is reporting that it wants. And so I call this goal alignment within Brian. And there's 200 plus actors that I'm currently asking their opinion of. And so I'm asking my liver, how are you doing? And it's expressing via the biomarkers. And so that I construct that diet and I only eat those foods until my next testing round. And that has changed my life more than I think anything else because in the demotion of my conscious mind that I gave primacy to my entire life, it led me astray because like you were saying, the mind then goes out into the world and it navigates the dozens of different dietary regimens people put together in books. And it's all has their supporting science in certain contextual settings, but it's not N of one. And like you're saying, this dietary really is an N of one. What people have published scientifically of course can be used for nice groundings, but it changes when you get to an N of one level. And so that's what gets me excited about brain interfaces is if I could do the same thing for my brain where I can stop asking my conscious mind for its advice or for its decision making, which is flawed. And I'd rather just look at this data and I've never had better health markers in my life than when I stopped actually asking myself to be in charge of it. The idea of demotion of the conscious mind is such a sort of engineering way of phrasing meditation. That's what we're doing, right? That's beautiful, that means really beautifully put. By the way, testing round, what does that look like? What's that? Well, you mentioned. Yeah, the test I do. Yes. So it includes a complete blood panel. I do a microbiome test. I do a diet induced inflammation. So I look for exotokine expressions. So foods that produce inflammatory reactions. I look at my neuroendocrine systems. I look at all my neurotransmitters. I do, yeah, there's several micronutrient tests to see how I'm looking at the various nutrients. What about self report of how you feel? Almost like, you can't demote your, you still exist within your conscious mind, right? So that lived experience is of a lot of value. So how do you measure that? I do a temporal sampling over some duration of time. So I'll think through how I feel over a week, over a month, over three months. I don't do a temporal sampling of if I'm at the grocery store in front of a cereal box and be like, you know what, Captain Crunch is probably the right thing for me today because I'm feeling like I need a little fun in my life. And so it's a temporal sampling. If the data sets large enough, then I smooth out the function of my natural oscillations of how I feel about life where some days I may feel upset or depressed or down or whatever. And I don't want those moments to then rule my decision making. That's why the demotion happens. And it says, really, if you're looking at health over a 90 day period of time, all my 200 voices speak up on that interval. And they're all given voice to say, this is how I'm doing and this is what I want. And so it really is an accounting system for everybody. So that's why I think that if you think about the future of being human, there's two things I think that are really going on. One is the design, manufacturing, and distribution of intelligence is heading towards zero on a cost curve over a certain design, over a certain timeframe that our ability to, you know, evolution produced us an intelligent form of intelligence. We are now designing our own intelligence systems and the design, manufacturing, distribution of that intelligence over a certain timeframe is going to go to a cost of zero. Design, manufacturing, distribution of intelligence cost is going to zero. For example. Again, just give me a second. That's brilliant, okay. And evolution is doing the design, manufacturing, distribution of intelligence. And now we are doing the design, manufacturing, distribution of intelligence. And the cost of that is going to zero. That's a very nice way of looking at life on Earth. So if that's going on and then now in parallel to that, then you say, okay, what then happens if when that cost curve is heading to zero? Our existence becomes a goal alignment problem, a goal alignment function. And so the same thing I'm doing where I'm doing goal alignment within myself of these 200 biomarkers, where I'm saying, when Brian exists on a daily basis and this entity is deciding what to eat and what to do and et cetera, it's not just my conscious mind, which is opining, it's 200 biological processes and there's a whole bunch of more voices involved. So in that equation, we're going to increasingly automate the things that we spend high energy on today because it's easier. And now we're going to then negotiate the terms and conditions of intelligent life. Now we say conscious existence because we're biased because that's what we have, but it will be the largest computational exercise in history because you're now doing goal alignment with planet Earth, within yourself, with each other, within all the intelligent agents we're building, bots and other voice assistants. You basically have a trillions and trillions of agents working on the negotiation of goal alignment. Yeah, this is in fact true. And what was the second thing? That was it. So the cost, the design, manufacturing, distribution of intelligence going to zero, which then means what's really going on? What are we really doing? We're negotiating the terms and conditions of existence. Do you worry about the survival of this process that life as we know it on Earth comes to an end or at least intelligent life, that as the cost goes to zero something happens where all of that intelligence is thrown in the trash by something like nuclear war or development of AGI systems that are very dumb, not AGI I guess, but AI systems, the paperclip thing, en masse is dumb but has unintended consequences where it destroys human civilization. Do you worry about those kinds of things? I mean, it's unsurprising that a new thing comes into the sphere of human consciousness. Humans identify the foreign object, in this case, artificial intelligence. Our amygdala fires up and says scary, foreign, we should be apprehensive about this. And so it makes sense from a biological perspective that humans, the knee jerk reaction is fear. What I don't think has been properly weighted with that is that we are the first generation of intelligent beings on this Earth that has been able to look out over their expected lifetime and see there is a real possibility of evolving into entirely novel forms of consciousness, so different that it would be totally unrecognizable to us today. We don't have words for it, we can't hint at it, we can't point at it, we can't, you can't look in the sky and see that thing that is shining, we're gonna go up there. You cannot even create an aspirational statement about it. And instead we've had this knee jerk reaction of fear about everything that could go wrong. But in my estimation, this should be the defining aspiration of all intelligent life on Earth that we would aspire, that basically every generation surveys the landscape of possibilities that are afforded, given the technological, cultural and other contextual situation that they're in. We're in this context, we haven't yet identified this and said, this is unbelievable, we should carefully think this thing through, not just of mitigating the things that'll wipe us out, but we have this potential, and so we just haven't given voice to it, even though it's within this realm of possibilities. So you're excited about the possibility of superintelligence systems and the opportunities that bring, I mean, there's parallels to this, you think about people before the internet as the internet was coming to life, I mean, there's kind of a fog through which you can't see, what does the future look like? Predicting collective intelligence, which I don't think we're understanding that we're living through that now, is that there's now, we've in some sense stopped being individual intelligences and become much more like collective intelligences, because ideas travel much, much faster now, and they can, in a viral way, sweep across the populations, and so it's almost, I mean, it almost feels like a thought is had by many people now, thousands or millions of people as opposed to an individual person, and that's changed everything, but to me, I don't think we're realizing how much that actually changed people or societies, but to predict that before the internet would have been very difficult, and in that same way, we're sitting here with the fog before us, thinking, what is superintelligence systems, how is that going to change the world? What is increasing the bandwidth, like plugging our brains into this whole thing, how is that going to change the world? And it seems like it's a fog, you don't know, and it could be, it could, whatever comes to be, could destroy the world, we could be the last generation, but it also could transform in ways that creates an incredibly fulfilling life experience that's unlike anything we've ever experienced. It might involve dissolution of ego and consciousness and so on, you're no longer one individual, it might be more, you know, that might be a certain kind of death, an ego death, but the experience might be really exciting and enriching, maybe we'll live in a virtual, like it's like, it's funny to think about a bunch of sort of hypothetical questions of would it be more fulfilling to live in a virtual world? Like if you were able to plug your brain in in a very dense way into a video game, like which world would you want to live in? In the video game or in the physical world? For most of us, we're kind of toying it with the idea of the video game, but we still want to live in the physical world, have friendships and relationships in the physical world, but we don't know that, again, it's a fog, and maybe in 100 years, we're all living inside a video game, hopefully not Call of Duty, hopefully more like Sims 5, which version is it on? For you individually though, does it make you sad that your brain ends? That you die one day very soon? That the whole thing, that data source just goes offline sooner than you would like? That's a complicated question. I would have answered it differently in different times in my life. I had chronic depression for 10 years, and so in that 10 year time period, I desperately wanted lights to be off, and the thing that made it even worse is I was in a religious, I was born into a religion. It was the only reality I ever understood, and it's difficult to articulate to people when you're born into that kind of reality and it's the only reality you're exposed to, you are literally blinded to the existence of other realities because it's so much the in group, out group thing, and so in that situation, it was not only that I desperately wanted lights out forever, it was that I couldn't have lights out forever. It was that there was an afterlife, and this afterlife had this system that would either penalize or reward you for your behaviors, and so it was almost like this, this indescribable hopelessness of not only being in hopeless despair of not wanting to exist, but then also being forced to exist, and so there was a duration of my time, a duration of life where I'd say, like yes, I have no remorse for lights being out, and I actually want it more than anything in the entire world. There are other times where I'm looking out at the future and I say this is an opportunity for a future evolving human conscious experience that is beyond my ability to understand, and I jump out of bed and I race to work and I can't think about anything else, but I think the reality for me is, I don't know what it's like to be in your head, but in my head, when I wake up in the morning, I don't say good morning, Brian, I'm so happy to see you. Like I'm sure you're just gonna be beautiful to me today. You're not gonna make a huge long list of everything you should be anxious about. You're not gonna repeat that list to me 400 times. You're not gonna have me relive all the regrets I've made in life. I'm sure you're not doing any of that. You're just gonna just help me along all day long. I mean, it's a brutal environment in my brain, and we've just become normalized to this environment that we just accept that this is what it means to be human, but if we look at it, if we try to muster as much soberness as we can about the realities of being human, it's brutal. If it is for me, and so am I sad that the brain may be off one day? It depends on the contextual setting. Like how am I feeling? At what moment are you asking me that? And my mind is so fickle. And this is why, again, I don't trust my conscious mind. I have been given realities. I was given a religious reality that was a video game. And then I figured out it was not a real reality. And then I lived in a depressive reality, which delivered this terrible hopelessness. That wasn't a real reality. Then I discovered behavioral psychology, and I figured out how biased, 188 chronicle biases, and how my brain is distorting reality all the time. I have gone from one reality to another. I don't trust reality. I don't trust realities are given to me. And so to try to make a decision on what I value or not value that future state, I don't trust my response. So not fully listening to the conscious mind at any one moment as the ultimate truth, but allowing it to go up and down as it does, and just kind of being observing it. Yes, I assume that whatever my conscious mind delivers up to my awareness is wrong upon landing. And I just need to figure out where it's wrong, how it's wrong, how wrong it is, and then try to correct for it as best I can. But I assume that on impact, it's mistaken in some critical ways. Is there something you can say by way of advice when the mind is depressive, when the conscious mind serves up something that, dark thoughts, how you deal with that, like how in your own life you've overcome that, and others who are experiencing that can overcome it? Two things. One, those depressive states are biochemical states. It's not you. And the suggestions that these things, that this state delivers to you about suggestion of the hopelessness of life or the meaninglessness of it, or that you should hit the eject button, that's a false reality. And that it's when, I completely understand the rational decision to commit suicide. It is not lost on me at all that that is an irrational situation, but the key is when you're in that situation and those thoughts are landing, to be able to say, thank you, you're not real. I know you're not real. And so I'm in a situation where for whatever reason I'm having this neurochemical state, but that state can be altered. And so again, it goes back to the realities of the difficulties of being human. And like when I was trying to solve my depression, I tried literally, you name it, I tried it systematically, and nothing would fix it. And so this is what gives me hope with brain interfaces, for example, like, could I have numbers on my brain? Can I see what's going on? Because I go to the doctor and it's like, how do you feel? I don't know, terrible. Like on a scale from one to 10, how bad do you want to commit suicide? 10. Okay, here's his bottle. How much should I take? Well, I don't know, like just. Yeah, it's very, very crude. And this data opens up the, yeah, it opens up the possibility of really helping in those dark moments to first understand the ways, the ups and downs of those dark moments. On the complete flip side of that, right, I am very conscious in my own brain and deeply, deeply grateful that what there, it's almost like a chemistry thing, a biochemistry thing that I go many times throughout the day. I'll look at like this cup and I'll be overcome with joy how amazing it is to be alive. Like I actually think my biochemistry is such that it's not as common, like I've talked to people and I don't think that's that common. Like it's a, and it's not a rational thing at all. It's like, I feel like I'm on drugs and I'll just be like, whoa. And a lot of people talk about like the meditative experience will allow you to sort of, you know, look at some basic things like the movement of your hand as deeply joyful because it's like, that's life. But I get that from just looking at a cup. Like I'm waiting for the coffee to brew and I'll just be like, fuck, life is awesome. And I'll sometimes tweet that, but then I'll like regret it later, like, God damn it, you're so ridiculous. But yeah, so, but that is purely chemistry. Like there's no rational, it doesn't fit with the rest of my life. I have all this shit, I'm always late to stuff. I'm always like, there's all this stuff, you know, I'm super self critical, like really self critical about everything I do, to the point I almost hate everything I do, but there's this engine of joy for life outside of all that. And that has to be chemistry. And this flip side of that is what depression probably is, is the opposite of that feeling of like, cause I bet you that feeling of the cup being amazing would save anybody in a state of depression. Like that would be like fresh, you're in a desert and it's a drink of water, shit man. The brain is a, it would be nice to understand where that's coming from, to be able to understand how you hit those lows and those highs that have nothing to do with the actual reality. It has to do with some very specific aspects of how you maybe see the world, maybe, it could be just like basic habits that you engage in and then how to walk along the line to find those experiences of joy. And this goes back to the discussion we're having of human cognition is in volume, the largest input of raw material into society. And it's not quantified. We have no bearings on it. And so we just, you wonder, we both articulated some of the challenges we have in our own mind. And it's likely that others would say, I have something similar. And you wonder when you look at society, how does that contribute to all the other compounder problems that we're experiencing? How does that blind us to the opportunities we could be looking at? And so it really, it has this potential distortion effect on reality that just makes everything worse. And I hope if we can put some, if we can assign some numbers to these things and just to get our bearings, so we're aware of what's going on, if we could find greater stabilization in how we conduct our lives and how we build society, it might be the thing that enables us to scaffold. Because we've really, again, we've done it, humans have done a fantastic job systematically scaffolding technology and science and institutions.
