格雷格·布羅克曼高中時寫完了整本化學教科書,從原子的基本結構一直寫到量子力學。一個朋友跟他說,你不是博士,這本書不可能出版。於是他轉去建網站推廣自己的想法,然後撞上了程式設計。

數學、化學、程式設計,在他看來是同一件事的三個版本。你思考一個問題,把結論寫成人類可以共享的形式,存進知識的圖書館,然後別人可以拿去用。區別在槓桿:一篇數學證明可能只有領域裡的五個人會讀,一段程式卻能被地球上任何一個人拿去跑,而且規模可以無限放大。

這是布羅克曼對數字世界最核心的迷戀。一個人,一個想法,影響整個星球。這件事在物理世界裡幾乎做不到,在程式碼裡是日常。

公司是一個有自己意志的東西

順著這個邏輯往下推,他不太願意把人當成某種特殊存在。人是一套資訊處理系統,這個描述聽起來冷,但能解釋的東西很多。

網際網路的意義不在那些物理光纜。它的意義在於,一個人突然可以即時聯絡到地球上的任何另一個人,可以檢索到人類積累過的幾乎任何一條知識。這是人類整體能力的重新佈線。

再往外推一層,社會、經濟、一家公司,都是比個體更大的東西。公司裡每個人都在想自己的事,都在認真思考該做什麼,但公司作為整體會做出一些沒有人單獨計劃過的事。它構成一個有用的抽象,也是真正在做決定的那個東西。

我們把自己當成地球上最聰明的生物,但有一些比我們更大的系統,是我們所有人共同喂出來的。(格雷格·布羅克曼)

他提到阿西莫夫的《基地》。書裡有個概念叫“心理史學”:當個體數量大到萬億級別,你或許能預測那個巨大宏觀體會做什麼,而且預測結果幾乎不受個體意願影響。

電話同一天被兩個人發明

布羅克曼說他經常想另一件事:技術決定論。

電話是兩個人同一天發明的。愛因斯坦如果不出現,相對論也會被另一個人發現,可能晚二十年,但人類不會永遠錯過這些真理。這說明所有人都在同一批巨人的肩膀上,你能想到的東西,別人遲早也會想到。

你能改變的是時間線,不是方向。

那麼一個人到底能起什麼作用?他給出的答案很收斂:你唯一真正的自由度,是設定一項技術誕生時的初始條件。

網際網路就是例子。當年有不止一個團隊在做類似的東西,最後跑出來的是這一支,因為創造它的那群人真的相信“任何人都能接入”這件事,帶著很強的學術氣質,開放、互聯。接下來四十年,網際網路基本長成了那個樣子。今天這個方向可能在變,但最初那幾年的設定,決定了後面四十年的走向。

萊克斯補了一個例子:維基百科。如果維基百科當年上了廣告,今天的網際網路會是什麼樣?它大概是網際網路上最重要的公共資源,而它執行得如此之好,好到令人意外。建立者設定了初始條件,然後它自己往前跑了。

如果造出了 AGI,你問它什麼問題

萊克斯把話頭引向未來:假設你真的做出了一個能透過圖靈測試、能用自然語言交流的通用智慧系統,你見到它,第一個問題是什麼?

布羅克曼的回答沒有猶豫。

到了那一步,你已經造出了一個能塑造人類未來的系統,那你最該問它的,就是怎麼能讓這件事往好的方向走。(格雷格·布羅克曼)

萊克斯追問:你不去問同事,不去問伊利亞,你去問系統本身?布羅克曼說,和伊利亞、和這裡所有人的對話早就發生過了。你需要儘可能多的視角和智慧來回答這個問題,強大系統的回答是其中一個輸入,不是最終裁決。

他把這個時刻類比成核武器剛被造出來的那幾年。當時全世界最重要的問題就是:世界秩序接下來長什麼樣?人類怎麼才能作為一個物種活下來?

為什麼壞訊息總是傳播得更快

萊克斯丟擲一個觀察:絕大多數可能的 AGI 發展路徑也許是正面的,但公眾討論幾乎全部集中在負面路徑上。薩姆·哈里斯如此,甚至馬斯克本人也如此。思考災難似乎比思考繁榮更有吸引力。

布羅克曼拆成兩個問題來回答。

第一個是想象力的問題。1950 年,你要向一個人描述 Uber,得先描述網際網路、GPS、每個人口袋裡都有一部手機。就算這些都講清楚了,對方也很難真的在腦子裡建立起那個世界。人類歷史上每一次顛覆性技術都證明過這一點,而 AGI 比它們全都更具顛覆性。正面圖景難畫,原因在於它依賴太多尚未發生的中間環節。

第二個問題更根本:破壞比建設容易。造一個東西需要每個環節都對,毀一個東西只需要一個環節出錯。物理世界是這樣,思想世界也是這樣。所以很多人的思考在看到負面劇本的那一刻就停住了,不再往下想。

布羅克曼對此保留了一點樂觀。他認為正面願景是可以被討論的,而只要把“正面也存在”這個事實說出來,很多人會有反應。他們意識到自己長期只盯著一半的圖景。

OpenAI 的三條腿

外界常有一個困惑:OpenAI 一邊說這東西有巨大風險,一邊拼命要把它造出來,這兩件事怎麼自洽?

布羅克曼的答案是看結構。OpenAI 有三塊主要業務:Capabilities 做技術、推進系統能力邊界;Safety 研究技術手段,確保造出來的系統與人類價值對齊;Policy 處理治理機制,回答那個繞不過去的問題:到底是誰的價值觀。

技術安全這一塊被討論得最多,科幻電影裡的反烏托邦基本都是技術安全失守的劇本。布羅克曼說,很多人看到“人類到底想要什麼”這個問題就卡住了。我怎麼把這個寫下來?我能寫清楚自己想要什麼嗎?寫不了。然後他們就在這裡停下了。

他的反駁是:我們已經造出了能學習人類無法明確規定的系統。識別一張圖裡是貓還是狗,規則根本寫不出來,但模型能學會。既然這樣,人類偏好也可能被學習。OpenAI 技術安全團隊的核心方向就落在這裡,他說已經有一些令人鼓舞的進展。

人類嬰兒可能長成一個好人,也可能長成一個壞人,很大程度取決於他從資料裡學到了什麼。我們唯一擁有的通用智慧樣本,就是靠反饋和資料學會人類價值的。那我們對機器用同樣的方法,不該感到意外。(格雷格·布羅克曼)

技術問題解決了,接下來是誰的操作員

布羅克曼認為真正的難題在政策這一層,而且被嚴重低估了。

假設最理想的情況:技術安全全部搞定,系統完全聽話,操作員讓它做什麼它就做什麼。那麼最重要的問題立刻變成:誰是操作員?他想要什麼?這會如何影響其他所有人?

這個問題不需要上升到存在主義的高度就能感受到難度。你只要看看世界上不同國家、不同文化對“社會應該怎麼運轉”的理解差異有多大,就知道“什麼是好的”這件事本身沒有現成答案。

他描述的理想狀態很具體:美國、中國、俄羅斯,以及另外幾百個國家,都能繼續按自己認為合適的方式存在,同時這個世界裡有一套極其強大的系統在人類身邊運轉,結果是人的存在變得更有意義,人更幸福、更富有、能過更充實的生活。

一旦你真的擁有了那個強大系統,怎麼設計這個世界並不是顯然的事。

2015 年 7 月的那頓晚飯

OpenAI 成立於 2015 年。布羅克曼說,起點來自一個很樸素的問題:這個領域已經有六七十年曆史了,如果人類智力勞動可以被自動化,什麼會變成可能?

這個問題被反覆問過,也被反覆辜負過。兩次 AI 寒冬之後,整個圈子幾乎不敢再做夢,公開談論 AGI 在學術共同體裡近乎禁忌。

他認為大家從歷史裡學錯了東西。

1959 年感知機發布,《紐約時報》那篇報道說這東西將來能識別面孔、叫出名字、實時翻譯語音。當時的人看了系統,說它什麼都做不了,然後花了十年時間試圖證明感知機這條路走不通,成功了,經費全斷,人們轉向別的方向。八十年代有一波復興,他以前一直聽說那是因為反向傳播演算法被髮明出來了。查了當年的文章才發現因果是反的:是個人電腦的普及讓更大的神經網路跑得起來了,人才興奮起來,反向傳播是隨後的事。

而那時候所謂的“更大的神經網路”,也就二十個神經元。二十個神經元能學到什麼?當然出不了好結果。

直到 2012 年,這個五十年代就提出的、最簡單最自然的方法,突然成了解決各類問題的最好辦法。他列出深度學習的三個性質:

  • 通用性:一小套工具,深度神經網路加上一些強化學習,能解決語音識別、機器翻譯、遊戲博弈等一大批完全不同的問題。
  • 有效性:四十年積累的傳統計算機視覺方法,被一個深度網路替換掉,效果更好。
  • 可擴充套件性:更大的網路、更多算力、更多資料,效果會繼續變好。這一條被反覆驗證。

這三條加在一起,第一次讓人感覺到通往通用智慧的路徑是存在的。當然不意味著把現有系統放大就自動得到 AGI,推理這塊明顯還缺東西,但至少有了一個能被相信的正規化。

布羅克曼說,一旦你真的相信這件事可能發生,而且可能比多數人預期的更早,你看自己的方式就變了。你不再想自己,你開始想怎麼讓這件事順利發生,怎麼把人和資源組織起來,以及萬一成功了,那個世界是不是我們真的想生活的世界。

一切順序都反了

正常公司的路徑是:創始人和 CEO 起步,做產品,拿使用者,找到產品市場契合,融資,招人,擴張,然後大公司發現你存在,試圖弄死你。OpenAI 的順序完全相反。

2015 年 7 月那頓晚飯,討論的核心問題只有一個:現在才開始建一個實驗室,還來得及嗎?

AI 正在從學術追求變成工業追求,最好的人都在大公司的研究實驗室裡,OpenAI 無論攢多少資源,和巨頭比都是蒼白的。而且不是兩個人寫個產品就行,你至少需要五到十個人的臨界規模。

他們的結論很剋制:這件事並非顯然不可能。既然並非顯然不可能,就值得一試。

一個上限被寫死的公司

2019 年,OpenAI 成立了 OpenAI LP,一個 capped-profit 實體。原來的非營利機構繼續存在,持有 OpenAI 非營利的名號。萊克斯請他解釋這個結構的由來。

布羅克曼的回答從使命開始:確保通用人工智慧惠及所有人。實現這個使命的主要方式是 OpenAI 自己去造,然後讓收益流向全世界。同時他們也接受別人造出來,只要收益沒有被鎖死在一家公司、一群人手裡。這兩條路都寫進了章程,也寫進了 LP 的結構。

所謂 capped,是說如果 OpenAI 真的成功了,投資人可以拿到回報,但回報有上限。通用人工智慧創造的價值會以數量級超過任何現有公司,而這些價值在法律上歸非營利機構所有,用來完成使命。

為什麼需要這個結構?因為兩年前他們意識到,要造 AGI,需要的錢遠超一個非營利機構能募到的規模。不是幾億,是幾十億美元。

於是問題變成:怎麼拿到這些錢,同時不背叛使命?他們把市面上所有法律結構都看了一遍,沒有一個合適。布羅克曼說這其實不奇怪,你要做的事前所未有,那用來做它的結構大概也得前所未有。

我們花了大約一年時間起草 OpenAI 章程。你看第一條就寫著,我們預計要調動巨量資源,但我們要確保與使命之間的利益衝突被降到最低。(格雷格·布羅克曼)

對齊“我們到底代表什麼”這件事,是設計整個結構的起點。

章程裡埋著的兩條路

章程裡其實同時寫了兩條路:我們主要靠自己造 AGI,但別人造出來我們也接受。布羅克曼承認這對一家公司來說很怪。

他說這正是設計 LP 時的核心張力。一方面,你要有成為主要參與者的可能性,而這真的需要建組織、募巨資、有執行一個極難願景的意志力,需要簽下一段很長的痛苦和風險。通常的做法就是匯入創業公司心態,全力競爭。

另一方面,真正的使命落在“AGI 對全人類是好的”上面,而不是“由 OpenAI 造出 AGI”。那麼你做的每一件事,都不能把那些同樣符合使命的正面結果關在門外。

百分之百倒向任何一邊都是錯的。他提到自己腦子裡始終有一根弦:不要只對外說 OpenAI 的目標是造 AGI,這個說法太窄了。第一,目標裡必須包含“安全”;第二,目標不是由我們造出來。

非營利太純,營利太滿

萊克斯提了一個直接的問題:為什麼一家營利公司就不能對世界好?谷歌大部分收入來自廣告,這不代表它不能做好事。利潤本身不必然損害影響力,真正影響公司的是章程、文化、裡面的人,利潤只是燃料。

布羅克曼說這個問題背後纏著人類社會最古老的爭論之一。他給了一個經驗性的觀察:讓你列世界上最有影響力的非營利組織,很難;讓你列最有影響力的營利公司,很容易。今天世界的組織方式確實讓營利機構擁有巨大的影響力,其中一部分原因在於營利機構能自我維持,能靠自己的動量往前滾。

這套機制的副作用也很真實。伐木公司開進雨林,那是我們不想要的結果,問題出在護欄沒設好。

他接著做了個類比,這個類比是整段對話裡最鋒利的地方:怎麼讓一家營利公司產生正面效益,和怎麼讓一個 AGI 產生正面效益,本質上是同一個問題。你有一個比任何人都強大、在多個維度上超越人類、某種程度上自主運轉的系統,你必須設好護欄。設好了,收益巨大。

非營利的問題是“發生的事太少”,它們很純粹,但推動事情很難。營利的問題是“發生的事太多”。如果形狀設計對了,它可以非常正面。OpenAI 走的是中間那條路。

他補充了一個容易被忽略的算術:在 OpenAI 成功的那個世界裡,創造的價值是天文數字,所以那個上限只佔其中很小一部分,投資人和員工拿到的回報,看起來和一家非常成功的創業公司差不多。他們最佳化的正是這個成功場景下的分配方式。

普通營利公司不同,它們的信託責任指向股東。在 OpenAI 的結構裡,信託責任指向章程,公司永遠可以做出章程認為正確的決定,即使這個決定損害股東利益。

董事會握著開關,員工握著鑰匙

章程裡有一條:避免讓 AGI 被用來不正當地集中權力。萊克斯問,OpenAI 自己為什麼不會把系統的全部權力攥在手裡?

答案分兩層。

結構上,決定 OpenAI 行動的權力最終歸屬於董事會,也就是非營利機構的董事會,它對完成非營利使命負有責任。這是把使命和公司綁在一起的方式。

日常層面是另一回事。董事會決定大方向,真正握著技術王國鑰匙的是每天在這裡幹活的員工。這一層怎麼保證?布羅克曼說,答案和任何一家公司的價值觀如何落地是一樣的:你需要一群真的相信這個使命、相信章程的人,他們願意做對自己不利但對章程有利的選擇。這是文化,也是一件必須長期努力維護的事。

他舉了一個大公司很難做到的點:在巨頭裡,一個基層員工很難走到 CEO 面前說我覺得我們做錯了。但在這裡,任何人都可以隨時把布羅克曼或薩姆拉到一邊說這件事,而且經常發生。他提到谷歌員工圍繞 Maven 專案發起的那次集體行動,說別的公司也許有自己的機制,但在這裡這件事的門檻極低。

競賽一旦開跑,安全就是第一個被扔掉的東西

章程裡還有一條:在後期從競爭轉向合作。萊克斯問這條怎麼落地。

布羅克曼說,假設技術問題解決了,部署 AGI 有兩個關鍵難題。

第一個是造出第一個 AGI 之前的軍備競賽。看自動駕駛就知道了,這裡是競爭性的比賽,而競爭性比賽裡永遠會發生的事就是:巨大的壓力會讓人把安全砍掉。

他最擔心的是這個場景:多個團隊都發現自己能做到,但走慢一點、更安全的路線會輸,於是大家都選快的那條。

OpenAI 想做的是不製造這場競賽。如果競賽已經在跑,別人跑在前面,他們不打算去跨過去,而是去幫對方成功,只要對方的目標是完成同一個使命。這件事不必自己來做。

但這個承諾不能是單方面的。布羅克曼強調,其他認真做 AGI 的玩家也應該做出類似承諾。如果所有人都相信 AGI 應該惠及所有人,那麼是哪家公司造出來的,其實不該重要。所有人都該擔心的,是為了搶先而跑得太急,結果出了事。

現在不是監管的時候,是測量的時候

萊克斯問政府對這一領域的角色。

布羅克曼說政府必須在場,這不用討論。他們做了多次國會聽證,和不少議員交流過。目前傳達的核心資訊是:現在不是監管的時候,是測量的時候。

具體建議是讓政府投入精力搞清楚技術現在到哪一步了、跑得多快,讓監管者真的具備判斷力。

不過他把這件事分了兩個層次。

對於當下的窄應用,已經存在合適的監管機構。自動駕駛該由 NHTSA 管,這很合理,因為這些系統在做的是人類已經在做的事,我們已經有關於標準和安全的思考框架,現在就該給這些機構授權。

對於 AGI,將來會有更好的答案,先測量,再討論規則。他特別提醒,過早扼殺一個正在成長的領域非常容易,這是必須避免的。他隨即補了一句:避免扼殺的方式不能是關起門來自己往前衝、把其他利益相關方排除在外。

GPT-2 不釋出的那個決定

2019 年 2 月,OpenAI 釋出了 GPT-2 的論文,但沒有放出完整模型,理由是擔心模型被濫用。萊克斯說,光是這個決定本身就有意思,因為它逼著整個社會開始討論這件事。

布羅克曼先講了背景。語言模型的路徑很清楚:把模型放大,效果會出現質的提升。GPT-2 只是把 2018 年 6 月釋出的那個模型放大了很多倍,然後就突然開始寫出連貫的散文,這是之前沒見過的。

那接下來呢?放大十倍、一百倍、一千倍,會發生什麼沒人知道。

6 月的那個模型,他們判斷是安全的,算學術作品,能帶來的正面價值遠大於潛在危害。到了 GPT-2,能力已經實質性增強,必須有一條線,從這條線開始認真考慮安全問題。

這條線畫在哪裡,內部爭議很大。宣佈不釋出之後,外面的反應同樣分裂:一批人說這顯然該釋出,另一批人說這顯然不該釋出。

如果一件事是否有益並不明顯,你大概應該預設選擇謹慎。幾乎可以確定,不釋出是對的決定。(格雷格·布羅克曼)

他把這次決定當成一個測試案例。真正要回答的問題在更後面:一個社會怎麼從“完全沒有負責任披露這個概念”,走到“我們有強大模型,先走個流程想一想”。

安全社群建立這套規範花了很多年。你發現一個漏洞,報給公司,公司可能起訴你,也可能根本不理你。那怎麼辦?永遠公開漏洞嗎?聽起來也不好。最後形成的是一整套共識:交給公司,公司在一定時間內不處理,你就可以公開,而且你不是壞人,你做對了。

布羅克曼說 AI 領域眼下完全沒有這套東西,GPT-2 就是一次演練。

和機器人區分這件事,註定要輸

萊克斯把話題推向一個更大的問題:如果假新聞可以用越來越聰明的方式生產、透過複雜的網路傳播、混在真人的原創想法裡,我們怎麼辦?有兩種世界。一種是人類永遠能設計出識別機器人的系統,另一種是我們接受自己在假資訊的海里游泳。

布羅克曼引用了那個流行梗圖:機械臂拿著筆點“我不是機器人”。

真正試圖區分機器和人類,最終是一場必輸的戰爭。(格雷格·布羅克曼)

他拿驗證碼舉例。最早的驗證碼就是一張簡單的圖,因為當時的 OCR 很差,加幾個干擾點,人還認得出來,機器不行。今天呢,他自己都經常做不出來。驗證碼只在某個階段成立,隨著 AI 變強,那些人類很容易、機器做不到的任務會越來越少。

但希望還在,方向要換。人類早就有身份認證的方式:社保號,把現實世界的身份和數字身份繫結的各種機制。他更看好的路是驗證內容的來源,而不是驗證內容本身。

代價是隱私和匿名性。如果唯一可信的內容是能追溯來源的內容,匿名還怎麼存在?他提出聲譽網路可能是一個解法,但也承認這個問題沒有顯然的答案。

他對當下的判斷很具體:今天他讀到一條推文,會隱約感覺這是真人寫的,或者感覺不太像。將來這種感覺會失效。他舉了 FCC 網路中立性意見徵集,後來發現其中數百萬條是自動生成的,研究者當時還能用統計方法識別出來。等到統計方法也失效呢?等到最有說服力的論證是 AI 寫的呢?他說,這已經不能算科幻了。

欺騙要劃紅線,陪伴不必

萊克斯把問題反過來問:為什麼和 AI 互動這件事本身是個問題?為什麼思想不能來自用人類資料訓練出來的模型?

布羅克曼的答案很剋制。他說有一條線必須劃死,就是欺騙。圖靈測試式的場景裡,一個 AI 假裝成人來騙你,這感覺是錯的。人需要對自己所處的環境有掌控感,需要知道對面是 AI 還是人,不能在這件事上被蒙。

另一件事他覺得完全可以。他又提到電影《她》,說這部片最好的一點是,它一開始就在問虛擬關係能有多真實,然後你跟著主角一起被捲進去,所有情緒按鈕被觸發的方式和對面是真人時一模一樣。

一個好笑的段子,有時候是不是人寫的並不重要。我們造 AI 的目的是增強人的生活,讓人能做更多事,讓人更充實。如果能做到,我籤。(格雷格·布羅克曼)

語言模型離推理還有多遠

萊克斯問:光靠無監督語言建模,能走到圖靈測試嗎?

布羅克曼說圖靈測試真正考的是推理,語言只是外殼。真要過測試,他得能教對面微積分,對面真的懂了,還能解新的微積分題。語言模型做不到這一層,需要把推理接進去。至於接的方式是全新的想法,還是對現有系統稍作改造,這是開放問題。

但他也強調,語言模型已經走得比很多人預期的遠。GPT-2 讀到“水下著火”這類描述時可能確實不理解那是什麼,但它也知道煙來自火,這些是從靜態文字里學到的,它沒有身體,沒有物理經驗。

至於“把 GPT-2 放大就能長出推理嗎”,他判斷不太可能。他給了一個技術上的說法:型別簽名不對。

人類思考的時候會投入可變的算力,想得越久答案越好。這個“多花算力換更好答案”的簽名,沒有被編碼進語言模型。模型在進化史上花了極長時間把預測這件事做到極致,但執行時只做一次前向傳播就往外吐字。要讓簽名對上,至少得做點改造,比如生成一整串思考過程,只保留最後收斂的那一段。

另一個缺失是分佈外泛化。遇到沒經歷過的東西,還能持續修正自己的心智模型,這件事在他看來同樣和推理糾纏在一起。可能只是一處小改動,也可能是需要幾十年的一堆新想法。

萊克斯在這裡開了個玩笑:也許從來就沒有什麼新想法,莎士比亞的所有故事拆開看都是愛與戲劇的不同排列。布羅克曼笑了,說確實。

薩頓那篇部落格被誤讀了

萊克斯提到理查德·薩頓的一篇博文,核心觀點是:七十年 AI 研究最大的教訓是,能利用算力的通用方法最終會贏。

布羅克曼說,那篇文章的反應很有意思,很多人讀成“算力就是一切”,並因此感到威脅。他不認為這是對的。演算法上的想法顯然極其重要,要造 AGI,算力規模和人類創造力兩邊都要推到極限。

但他認可那個問題的問法:我們應該追求什麼樣的想法?答案是那些可擴充套件的想法。一個想法如果投入更多算力、更多資料就會變得更好,那它就是聖盃。

萊克斯提出一個更現實的角度。一個十三歲的孩子坐在堪薩斯州某處,手上可能只有一塊 1080 顯示卡,甚至沒有 GPU。看到“規模決定一切”這種說法,他會覺得自己沒法參與。那麼要不要把算力的民主化看得和演算法民主化一樣重要?

布羅克曼把可能性空間切成兩塊。

一塊確實需要巨量算力,沒有捷徑,這也是 OpenAI 要建大叢集的原因。另一塊不需要,而且這塊裡的好想法有個特徵:放大後會變得更好,但你在小規模就能發現它。GAN 和 VAE 都是這樣的例子,實際做出它們的人當時也沒有海量算力。

不過他也補了一刀:最早的 GAN 生成結果相當糟糕。發明者聰明到知道這條路能走通,但東西本身還很粗糙。

他講了一個哈佛系統教授 Matt Welsh 的故事。Welsh 拿到終身教職的那場報告,布羅克曼就在臺下聽。那個夏天 Welsh 去了谷歌,然後決定不回學術界了。他在部落格裡寫:作為系統研究者,我做出漂亮的系統想法,做個原型,最好的結局是谷歌或雅虎的人把它實現、真的跑起來。我造了個小東西,他們造了個真正在運轉的大東西。我不想再當那個人了。

布羅克曼說這裡有個很個人化的取捨:你可以做提出想法、做出原型的人,你拿不到最酷的 GAN 影象,但 GAN 是你發明的。兩邊都有價值。

也有反例。2018 年 6 月那個模型在小規模時已經創下一些記錄,生成結果雖然遠不如 GPT-2 驚豔,但能看出苗頭。可是有時候規模會催生質變,湧現出小規模完全看不到的行為,連演算法最初的發明者都會說“我沒想到它能做這個”。

“我沒想到它能做到那個”

Dota 的故事就屬於這一類。

OpenAI 選 Dota 是因為它比國際象棋和圍棋更接近真實世界。棋類是純腦力的、離散的、回合制的。Dota 是連續時間,動作空間巨大,一局四十五分鐘,不同單位、大量混亂因素,之前的遊戲都沒捕捉到這些東西。而且所有手工寫的 Dota 機器人都是災難,根本沒法寫,太複雜了。

他們從一對一版本開始,用自我對弈:兩個什麼都不會的智慧體互打,其中一個摸索出一點優勢,另一個立刻也學會了,然後雙方無上限地互相推高。他們打贏了世界冠軍,技能曲線是乾淨的指數增長,人類迭代迴圈帶來了非常穩定的進步。

然後擴到五對五。這相當於從單挑變成籃球,需要大量團隊協同。同一套自我對弈方法,推到了職業水平。

布羅克曼有個比喻:這些智慧體更像昆蟲智慧。一隻昆蟲在環境裡活很久,把大量經驗烘進身體裡。它不會學微積分,但在自己的環境裡導航得極好,面對沒見過的東西也能應付。Dota 機器人也是這樣,它們要對抗人類,而人類這種事在其訓練環境里根本不存在,打法完全不同,但它們處理得很好。

這一點在小規模 PPO 上看不到。訓練用了十萬級別的 CPU 核心和幾百塊 GPU,每一天灌進機器人的經驗量,相當於數百年。在那種規模下,熟悉的老演算法開始表現出完全不同的行為。

2018 年國際邀請賽,OpenAI 上臺和世界頂級戰隊打了兩場,都輸了,但每場都打到二十五三十分鐘,來回拉鋸。他們判斷那已經是職業水平,只是運氣沒站在自己這邊。國際邀請賽的時間是固定的,他們只能在那一天之前把系統推到極限。兩週之後,對同樣的對手勝率大約八成。

所以那場比賽是一個快照,不是終局。布羅克曼說他們很快會宣佈最終一戰,對手是世界冠軍,比賽會在這期播客上線前公佈。但對他而言,成敗判定不在這裡。專案的目標從來都是推進強化學習的技術邊界,那個目標已經達到了。

專案有生命週期

萊克斯問未來幾年深度學習和強化學習往哪走。布羅克曼說方向和規模都要,缺一不可。

OpenAI 內部有一套專案生命週期。一開始是幾個人做一個小規模的想法,語言模型就是典型例子:很長一段時間只有一個人在推。然後出現生命跡象,比如初代 GPT 的效果讓人興奮,那就到了放大階段,加人、加算力,繼續推,最終形態像 Dota 或機器人那樣,十幾二十人的大團隊,大規模運轉,工程和機器學習研究擰在一起,做出否則根本不可能的結果。

這套流程他們跑過好幾輪,一個週期大概一到兩年。組織成立才三年多。

2019 年新開的一個團隊是 Reasoning Team,由伊利亞和另一位研究員牽頭,專門攻“怎麼讓神經網路推理”。布羅克曼預期這裡是長期專案。

萊克斯問,什麼樣的表現會讓你覺得推理真的成了?布羅克曼說邏輯,尤其是數學邏輯。他補充了幾類在他看來同構的問題:程式設計,甚至程式碼的安全分析,這些捕捉的是同一套核心推理能力,以及分佈外泛化。

萊克斯順勢開了個玩笑:如果 OpenAI 推理團隊證明了 P=NP,那挺好。布羅克曼說那會非常非常激動人心,尤其如果最後發現 P 確實等於 NP,那就更有意思了。

火星和木星之間有個茶壺

萊克斯問:我們是不是生活在模擬裡?

布羅克曼的回答方式很能說明他的思維習慣。他說自己會把問題分成兩類:能對世界給出可驗證的不同預測的,和只是好玩但不知道怎麼影響生活的。模擬假說在他這裡屬於後者,性質接近“火星和木星之間是不是飄著一個茶壺”。也許是,但很難說這對我的生活意味著什麼。

不過模擬在工程上確實有用。OpenAI 的機器手系統 Dactyl 就是在模擬裡訓練的,用的還是 Dota 那套系統,然後遷移到實體機器人上。外界總說這只是個遊戲,你怎麼可能跨到真實世界?答案是他們已經用一隻沒人能手工程式設計的機械手跨過去了。只要方法對,模擬能走的路比你想的遠得多。

但“模擬裡的智慧體會不會醒來、有沒有意識”,他覺得這個問題難得多。

二十個神經元和一隻貓

萊克斯追問:造通用智慧,需不需要意識?需不需要身體?

布羅克曼先給了不宏大的答案。看看已經在運轉的東西:很多人會說,要得到這些結果,你需要真實世界經驗,需要身體,需要 grounding,否則你怎麼理解煙和火?而 GPT-2 證明你可以走得比這種推理遠得多。它沒有身體,沒有意識,卻在某些維度上顯得通用了,雖然遠不如 AGI 那樣能幹、學得快。

所以答案大概是:不需要。至少現在這些系統不需要。

然後是宏大的那一半。如果神經網路已經有意識了,我們怎麼知道?

他提到動物身上明視訊記憶體在意識連續譜。他的貓有某種程度的意識,只是不如人。你可以想象造一臺意識測量儀,對著貓測出一個數字,對著人測出大得多的數字。那對著一個神經網路測呢?如果你在訓練一個巨大的模擬,裡面的網路會感到痛苦嗎?

他說,要確信答案是“不會”變得很難,要思考“如果是會”意味著什麼,也變得很難。

他給了一條可能的解釋路徑:也許人類有意識,是因為意識是一個方便的計算捷徑。一個需要躲避疼痛、需要進食才能生存的存在,最省事的實現方式可能就是讓它有意識。如果這個說法成立,那我們應該預期,足夠強的強化學習智慧體也會有某種意識。但這裡有個很大的“如果”,反方向的論證也不少。

萊克斯接過話頭說,覺得 GPT-2 有某種程度的意識,這個想法也許沒有想象中那麼瘋狂,就像我們討論狗的智慧、貓的智慧、人的智慧一樣。

最後一個問題,萊克斯問得很輕:我們會不會像《她》裡那樣,和 AI 相愛?或者 AI 愛上人類?

布羅克曼說,我希望會。

萊克斯說,用愛收尾再好不過了。

如果只記三件事

這期對話發生在 2019 年 4 月,GPT-2 剛釋出兩個月,OpenAI LP 剛成立一個月,Dota 的最終一戰還沒打。回頭看,布羅克曼當時說的很多判斷後來被驗證了,也有很多地方他自己承認不知道。對今天讀這段對話的人來說,真正有用的或許不是那些結論,是他處理問題的方式。

  • 判斷一個技術方向,先看它的可擴充套件性。一個想法如果投入更多算力、更多資料就變得更好,它值得押注;一個只能靠人工反覆調優才成立的想法,天花板擺在那裡。這個標準可以用來評估你自己在做的專案,也可以用來識別別人給你講的技術故事裡哪一部分是真的有生命力的。
  • 把“誰是操作員”當成必須回答的問題,別留到事後。技術安全解決的是系統聽不聽話,治理解決的是誰在說話、他的價值觀會影響誰。任何強能力系統上線之前,這兩個問題都得有答案,缺一個都不算完成。這條對做 AI 產品的人成立,對做任何有槓桿的工具的人也成立。
  • 遇到“有益還是有害並不明顯”的判斷,預設選謹慎。布羅克曼對 GPT-2 的處理邏輯可以遷移到很多場景:如果內行吵成一團、兩邊都有強論證,說明風險不對稱,此時不做的成本遠低於做錯的成本。真正需要警惕的是那種“顯而易見該發”的自信。
  • 在你沒有算力的方向上找可擴充套件的想法。GAN 和 VAE 都是在資源有限時被提出來的,它們的價值在於放大之後會更好。個人的策略很少是與巨頭比叢集規模,更可行的是去找那種“小規模能驗證、大規模會爆發”的想法,然後把它做出來當作證據。
  • 警惕競爭壓力對安全標準的侵蝕。軍備競賽裡第一個被砍掉的永遠是安全冗餘。如果你所在的團隊正在“慢一點更安全但會輸”和“快一點但有風險”之間做選擇,那說明賽道本身有問題,值得退出來重新看,或者像布羅克曼說的那樣,去找那個跑在前面的人合作,而不是加速跨過去。

[00:00:00] The following is a conversation with Greg Brockmann. He's the co-founder and CEO of Open Eye, a world class research organization, developing ideas and A.I. with a goal of eventually creating a safe and friendly artificial general intelligence, one that benefits and empowers humanity. Opening is not only a source of publications, algorithms, tools and data sets. [00:00:24] Their mission is a catalyst for an important public discourse about our future, with both narrow and general intelligence systems. This conversation is part of the Artificial Intelligence Podcast at MIT and beyond if you enjoy it. Subscribe on YouTube, iTunes or simply connect with me on Twitter at Lex Friedman spelled F.R. I.D.. And now here's my conversation with Greg Brockman. So in high school and right after you wrote a draft of a chemistry textbook, saw that that covers everything from basic structure, the atom to quantum mechanics. [00:01:18] So it's clear you have an intuition and a passion for both the the physical world with chemistry and now robotics to the digital world with a deep learning, reinforcement learning and so on. [00:01:32] Do you see the physical world in the digital world is different? And what do you think is the gap? [00:01:37] A lot of it actually boils down to iteration speed, right? That I think that a lot of what really motivates me is is building things right is the you know, think about mathematics, for example, where you think really hard about a problem. You understand that you're right down to this very obscure form they call proof. But then this is a humanities library, right? It's there forever. There's some truth that we've discovered. You know, maybe only five people in your field will ever read it, but somehow you kind of move humanity forward. [00:02:02] And so I actually used to really think that I was going to be a mathematician. And then I actually started writing this chemistry textbook. One of my friends told me you'll never publish it because you don't have a Ph.D. So instead I decided to build a website and try to promote my ideas that way. And then I discovered programming. And you know that programming you think hard about a problem. You understand that you write down in a very obscure form that we call a program. [00:02:27] But then once again, it's in humanities library. Right. And anyone could get the benefit from it. And the scalability is massive. And so I think that the thing that really appeals to me about the digital world is that you can have this this this insane leverage. Right. A single individual with an idea is able to affect the entire planet. And that's something I think is really hard to do if you're moving around physical atoms. [00:02:47] But you said mathematics. So if you look at the what things over here our mind, do you ultimately see it as just math is just information processing or is there some other magic as you've seen if you've seen the biology and chemistry and so on? [00:03:04] Yeah, I think it's really interesting to think about humans is just information processing systems. And that, it seems like, is actually a pretty good way of describing a lot of kind of how the world works are a lot of what we're capable of. To think that that, you know, again, if you just look at technological innovations over time, that in some ways the most transformative innovation that we've had has been the computer. Right. In some ways, the Internet, you know, that what is the Internet done? [00:03:27] Right. The Internet is not about these physical cables. It's about the fact that I am suddenly able to instantly communicate with any other human on the planet. I'm able to retrieve any piece of knowledge that in some ways the human race has ever had and that those are these insane transformations. [00:03:43] Do you see the our society as a whole, the collective as another extension of the intelligence of the human being? So if you look at the human beings information processing system, you mentioned the Internet, the networking. Do you see us all together as a civilization, as a as a kind of intelligent system? [00:03:58] Yeah, I think this is actually a really interesting perspective to take and to think about that. You sort of have this collective intelligence of all of society. The economy itself is the super human machine that is optimizing something. Right. And it's also in some ways, a company has a will of its own right. [00:04:15] That you have all these individuals who are all pursuing their own individual goals and thinking really hard and thinking about the right thing to do. But somehow the company does something that is this emergent thing and that is it's a really useful abstraction. And so I think that in some ways, you know, we think of ourselves as the most intelligent things on the planet and the most powerful things on the planet. But there are things that are bigger than us that are these systems that we all contribute to. [00:04:39] And so I think actually, you know, it's a it's interesting to think about if you've read Isaac Asimov Foundation, right. That that there's this concept of psychohistory in there, which is effectively this, that if you have trillions or quadrillions of of beings, then maybe you could actually predict what that being that that huge macro being will do and almost independent of what the individuals want. [00:04:59] And I actually have a second angle on this I think is interesting, which is thinking about technological determinism. [00:05:05] One thing that I actually think a lot about with with opening I right is that we're kind of coming on onto this insanely transformational technology of general intelligence. [00:05:14] Right. That will happen at some point. [00:05:16] And there's a question of how can you take actions that will actually steer it to go better rather than worse? And that I think one question I need to ask is, as a scientist, as an inventor, as a creator, what impact can you have in general? Right. You look at things like the telephone invented by two people on the same day, like what does that mean? Like what does that mean about the shape of innovation? And I think that what's going on is everyone's building on the shoulders of the same giants. [00:05:39] And so you can kind of you can't really hope to create something no one else ever would. You know, if Einstein wasn't born, someone else would have come up with relativity. You know, he changed the timeline a bit, right. That maybe it would take another 20 years, but it wouldn't be that fundamentally humanity would never discover these these fundamental truths. [00:05:54] So there's some kind of invisible momentum that some people like Einstein are opening eyes, plugging into that anybody else can also plug into. And ultimately, that wave takes us into a certain direction. That's that's right. That's right, and, you know, this kind of seems to play out and a bunch of different ways that there's some exponential that is being written and that the exponential itself, which one it is, changes. Think about Moore's Law. An entire industry set its clock to it for 50 years. [00:06:22] Like, how can that be right? How is that possible? And yet somehow it happened. And so I think you can't hope to ever invent something that no one else will. Maybe you can change the timeline a little bit, but if you really want to make a difference, I think that the thing that you really have to do, the only real degree of freedom you have is set the initial conditions under which a technology is born. [00:06:42] And so you think about the Internet, right, that there are lots of other competitors trying to build similar things and the Internet one, and that the initial conditions where that was created by this group that really valued people being able to be, you know, anyone being able to plug in this very academic mindset of of being open and connected. And I think that the Internet for the next 40 years really played out that way. You know, maybe today things are starting to shift in a different direction. [00:07:07] But I think that those initial conditions were really important to determine the next 40 years worth of progress. [00:07:12] That's really beautifully put. Another example of that I think about you know, I recently looked at it. [00:07:18] I looked at Wikipedia, the formation of Wikipedia, and I wonder what the Internet would be like if Wikipedia had ads. You know, there's an interesting argument that why they chose not to make it put advertising on Wikipedia. I think it's I think Wikipedia is one of the greatest resources we have on the Internet. And it is extremely surprising how well it works and how well it was able to aggregate all this kind of good information. And essentially the creator Wikipedia, I don't know, there's probably some debates there, but set the initial conditions and it carried itself forward. [00:07:50] That's really interesting. So you're the way you're thinking about ajai or artificial intelligence is you're focused on setting the initial conditions for the progress. [00:07:58] That's right. That's powerful. OK, so look into the future. If you create an AGI system like one that can answer Turing test natural language, what do you think would be the interactions you would have with it? [00:08:13] What do you think are the questions you would ask? Like what would be the first question you would ask it for him? That's right. [00:08:19] I think that at that point, if you've really built a powerful system that is capable of shaping the future of humanity, the first question that you really should ask is how do we make sure that this plays out well? And so that's actually the first question that I would ask a powerful ajai system is so you wouldn't ask your colleague, you wouldn't ask like Illia, you would ask the system. [00:08:39] Oh, we've already had the conversation with Iliya. Right. And everyone here. And so you want as many perspectives and piece of wisdom as you can for for answering this question. So I don't think you necessarily defer to whatever your powerful system tells you, but you use it as one input to try to figure out what to do. But I guess fundamentally what it really comes down to is if you've built something really powerful and you think about it, think about, for example, the creation of of shortly after the creation of nuclear weapons. [00:09:05] Right. The most important question in the world was what's the world order going to be like? How do we set ourselves up in a place where we're going to be able to survive as a species with ajai? [00:09:16] I think the question slightly different, right, that there is a question of how do we make sure that we don't get the negative effects. But there's also the positive side, right? You imagine that. You know, like like what won't it be like like what will be capable of? And I think one of the core reasons that in Ajai can be powerful and transformative is actually due to technological development. Right. If you have something that's capable, as capable as a human and that it's much more scalable, that you absolutely want that thing to go read the whole scientific literature and think about how to create cures for all the diseases. [00:09:47] Right. You want to think about how to go and build technologies to help us create material abundance and to figure out societal problems that we have trouble with, like how are we supposed to clean up the environment? [00:09:57] And, you know, maybe you want this to go and invent a bunch of little robots that'll go out and be biodegradable and turn ocean debris into harmless molecules. [00:10:06] And I think that that that positive side is something that I think people miss sometimes when thinking about what an ajai will be like. [00:10:15] And so I think that if you have a system that's capable of all of that, you absolutely want its advice about how do I make sure that we're using your your capabilities in a positive way for humanity. [00:10:26] So what do you think about that psychology that looks at all the different possible trajectories of an ajai system, many of which perhaps the majority of which are positive and nevertheless focuses on the negative trajectories? And you get to interact with folks who get to think about this maybe within yourself as well. You look at Sam Harris and so on. It seems to be sorry to put it this way, but almost more fun to think about the negative possibilities, whatever that's deep in our psychology. [00:10:56] What do you think about that and how do we deal with it? Because we want to help us. [00:11:01] So I think there's kind of two problems entailed in that question. The first is more of the question of how can you even picture what a world with a new technology will be like? Now, imagine we're in nineteen fifty and I'm trying to describe Uber to someone. [00:11:20] Apps and the Internet. Yeah, I mean, yeah, that's that's going to be extremely complicated, but it's imaginable. It's imaginable, right. [00:11:28] But and now imagine being in 1950 and predicting Uber. Right. And you need to describe the Internet. You describe GPS. You need to describe the fact that everyone's going to have this phone in their pocket. [00:11:41] And so I think that that just the first truth is that it is hard to picture how a transformative technology will play out in the world. We've seen that before with technologies that are far less transformative than ajai will be. And so I think that that one piece is that is just even hard to imagine and to really put yourself in a world where you can predict what that that positive vision would be like. [00:12:04] And, you know, I think the second thing is that it is I think it is always easier to support the negative side than the positive side. It's always easier to destroy than create. And, you know, in in a physical sense, a more just in an intellectual sense. Right. Because, you know, I think that with creating something, you need to just get a bunch of things right and to destroy you just need to get one thing wrong. [00:12:27] Yeah. And so I think that what that means is that I think a lot of people's thinking dead ends as soon as they see the negative story. [00:12:34] But that being said, I actually actually have some hope. Right. I think that the that the positive vision is something that I think can be is something that we can we can talk about. And I think that just simply saying this fact of. Yeah, like, that's positive. There's negatives. Everyone likes to dwell on the negative people that respond well to that message and say, ha, you're right, there's a part of us that we're not talking about, not thinking about. [00:12:56] And that's actually something that's that's that's, I think really been a key part of how we think about ajai at open. I right. You can kind of look at it as like, OK, like opening up talks about the fact that there are risks and yet they're trying to build the system. Like, how do you square that those two facts? [00:13:13] So do you share the intuition that some people have? [00:13:16] I mean, from Sam Harris to even Elon Musk himself, that it's tricky as you develop ajai to keep it from slipping into the existential threats, into the negative. [00:13:29] What's your intuition about how hard is it to keep a development on the positive track? [00:13:36] And what's your intuition there? [00:13:38] To answer the question, you can really look at how we structure open A.I. So we really have three main arms that we have capabilities which is actually doing the technical work and pushing forward what these systems can do. There's safety, which is working on technical mechanisms to ensure that the systems we build are aligned with human values. And then there's policy which is making sure that we have governance mechanisms answering that question of, well, who's values. And so I think that the technical safety one is the one that people kind of talk about the most. [00:14:07] Right. And you talk about like think about, you know, all of the dystopic AI movies. A lot of that is about not having good technical safety in place. And what we've been finding is that, you know, I think that actually a lot of people look at the technical safety problem and think it's just intractable. Right. This question of what do humans want? How am I supposed to write that down? Can I even write down what I want? [00:14:28] No way. And then they stop there. But the thing is, we've already built systems that are able to learn things that humans can't specify, you know, even the rules for how to recognize if there's a cat or dog in an image. Turns out it's intractable to write that down, and yet we're able to learn it and that what we're seeing with systems, we build it open and they're still in early proof of concept stage is that you are able to learn human preferences. [00:14:53] You're able to learn what humans want from data. And so that's kind of the core focus for our technical safety team. And I think that they're actually we've had some pretty encouraging updates in terms of what we've been able to make work. [00:15:05] So you have an intuition and a hope that from data, you know, looking at the value alignment problem from data, we can build systems that align with the collective better angels of our nature. So align with the ethics and the morals of human beings to even say this in a different way. [00:15:23] I mean, think about how how do we align humans, right? Think about like a human baby can grow up to be an evil person or a great person. And a lot of that is from learning from data. Right. That you have some feedback as a child is growing up. They get to see positive examples. And so I think that that just like that, the only example we have of a general intelligence that is able to learn from data to align with human values and to learn values, I think we shouldn't be surprised that we can do the same sorts of of techniques or whether the same sort of techniques end up being how we we saw value for ages. [00:15:58] So let's go even higher. I don't know if you've read the book Sapience, but there's an idea that you know that as a collective, as us human beings have kind of developed together and ideas that we hold, there's no in that context, objective truth. We just kind of all agree to certain ideas and hold them as a collective. [00:16:18] Did you have a sense that there is in the world of good and evil, do you have a sense to the first approximation, there are some things that are good and that you could teach systems to behave to be good. [00:16:31] So I think this actually blends into our 13 right. Which is the policy team. And this is the one aspect I think people really talk about way less than they should. Right. Because imagine that we build super powerful systems that we've managed to figure out all the mechanisms for these things to do whatever the operator wants. The most important question becomes who's the operator? What do they want and how is that going to affect everyone else? Right. And and I think that this question of what is good, what are those values? [00:17:01] I mean, I think you don't even have to go to those those very grand existential places to start to realize how hard this problem is. You just look at different countries and cultures across the world and that there's there's a very different conception of how the world works. And, you know, what what what kinds of ways that society wants to operate. And so I think that that that the really core question is, is actually very concrete. And I think it's not a question that we have ready answers to. [00:17:29] Right. [00:17:30] Is how do you have a world where all the different countries that we have the United States, China, Russia and, you know, the hundreds of other countries out there are able to continue to not just operate in the way that they see fit, but in the world that emerges in these where you have these very powerful systems operating alongside humans ends up being something that empowers humans more, that makes like human existence be a more meaningful thing, and that people are happier and wealthier and able to live more fulfilling lives. [00:18:06] It's not an obvious thing for how to design that world once you have that very powerful system. [00:18:10] So if we take a little step back and we're having like a fascinating conversation and open as in many ways a tech leader in the world, and yet we're thinking about these big existential questions, which is fascinating, really important. I think you're a leader in that space. And it's a really important space of just thinking how I affect society in a big picture view. [00:18:31] So Oscar Wilde said we're all in the gutter, but some of us are looking at the stars. And I think Open has a charter that looks to the stars, I would say, to create intelligence, to create general intelligence, make it beneficial, safe and collaborative. Can you tell me? [00:18:49] How that came about, how a mission like that and the path to creating a mission like that opening I was found. [00:18:56] Yeah. So I think that in some ways it really boils down to taking a look at the landscape right now. [00:19:02] If you think about the history of A.I., that basically for the past 60 or 70 years, people have thought about this goal of what could happen if you could automate human intellectual labor. [00:19:12] Right. Imagine you could build a computer system that could do that. What becomes possible? [00:19:17] We have a lot of sci fi that tells stories of various dystopias and, you know, increasingly of movies like her that tell you a little bit about maybe more of a little bit utopian vision. You think about the impacts that we've seen from being able to have bicycles for our minds and computers, and that I think that the that the impact of computers and the Internet has just far outstripped what anyone really could have predicted. And so I think that it's very clear that if you can build an ajai, it will be the most transformative technology that humans will ever create. [00:19:51] And so what it boils down to then is a question of, well, is there a path? Is there hope? Is there a way to build such a system? And I think that for 60 or 70 years that people got excited and that, you know, ended up not being able to deliver on the hopes that the people had pinned on them. And I think that then, you know, that after, you know, two two winters of development, the people I, you know, I think kind of almost stopped daring to dream. [00:20:17] Right. Really talking about ajai or thinking about ajai became almost this taboo in the community. [00:20:23] But I actually think that people took the wrong lesson from history. And if you look back starting in 1959 is when the Perceptron was released. And this is basically, you know, one of the earliest neural networks, it was released to what was perceived as this massive overhype. So in The New York Times in 1959, you have this article saying that, you know, the Perceptron will one day recognize people, call their names, instantly translate speech between languages and people at the time looked at this and said, this is your system, can't do any of that. [00:20:53] And basically spent 10 years trying to discredit the whole Perceptron direction. And it succeeded and all the funding dried up. And, you know, people kind of went in other directions. And, you know, the 80s there was a resurgence. And I'd always heard that the resurgence in the 80s was due to the invention of back propagation and these these algorithms that got people excited. But actually, the causality was due to people building larger computers that you can find these these articles from the 80s saying that the democratization of computing power suddenly meant you could run these larger neural networks. [00:21:21] And then people started to do all these amazing things back propagation algorithm was invented. And you know that the neural nets people were running were these tiny little like 20 neuron neural nets. Right. Right. Like, what are you supposed to learn with 20 neurons? [00:21:32] And so, of course, they weren't able to get great results. And it really wasn't until 2012 that this approach that's almost the most simple natural approach that people have come up with in the 50s. Right. In some ways, even in the 40s before there were computers with Pitts' McCallan, their neuron. Suddenly, this became the best way of solving problems, right, and I think there are three core properties that deep learning has that I think are very worth paying attention to. [00:22:01] The first is generality with a very small number of deep learning tools, deep, deep neural net, maybe some some, you know, RL and it solves this huge variety of problems, speech recognition, machine translation, game playing, all of these problems, a small set of tools. So there's the generality. There's a second piece, which is the competence. You want to solve any of those problems throughout 40 years worth of normal computer vision research replaced with deep neural net. [00:22:29] It's going to work better. And there's a third piece, which is the scalability. Right? The one thing that has been shown time and time again is that you if you have a larger neural network through more compute, more data, add it, it will work better. Those three properties together feel like essential parts of building a general intelligence. [00:22:48] Now, it doesn't just mean that if we scale up what we have, that we will have an ajai right. [00:22:52] There are clearly missing pieces. There are missing ideas. We need to have answers for reasoning. But I think that the core here is that for the first time, it feels that we have a paradigm that gives us hope the general intelligence can be achievable. And so as soon as you believe that everything else becomes comes into focus. Right. If you imagine that you may be able to and you know that the timeline, I think, remains uncertain. But I think that that, you know, certainly within our lifetimes and possibly within a much shorter period of time than than people would expect, if you can really build the most transformative technology that will ever exist, you stop thinking about yourself so much. [00:23:29] Right. And you start thinking about just like how do you have a world where this goes well and that you need to think about the practicalities of how do you build an organization and get together a bunch of people and resources and to make sure that people feel motivated and ready to do it. [00:23:45] But I think that then you start thinking about, well, what if we succeed and how do we make sure that when we succeed that the world is actually the place that we want ourselves to exist? And, you know, almost the results in Bell sense of the word. And so that's kind of the broader landscape and opening. I was really formed in 2015 with that high level picture of ajai might be possible sooner than people think and that we need to try to do our best to make sure it's going to go well. [00:24:14] And then we spent the next couple of years really trying to figure out what does that mean, how do we do it? And, you know, I think that typically with a company, you start out very small CEO and co-founder, and you build a product, you get some users, you get product market fit. You know, at some point you raise some money, you hire people, you scale, and then you go down the road. [00:24:33] Then the big companies realize you exist and try to kill you. And for opening I it was basically everything and exactly the opposite order. [00:24:42] Let me just pause for a second. He said a lot of things. Let me just admire the jarring aspect of what open A.I. stands for, which is daring to dream. I mean, you said it's pretty powerful. You caught me off guard because I think that's very true. [00:24:57] The the the step of just daring to dream about the possibilities of creating intelligence in a positive and a safe way. But just even creating intelligence is a much needed, refreshing catalyst for the AI community. So that's that's the starting point. OK, so then formation of open. [00:25:18] I, uh, what I would just say that, you know, when we were starting opening AI, that kind of the first question that we had is, is it too late to start a lab with a bunch of the best people possible? [00:25:30] That was an actual question was are those those are the core question of of you know, we have this dinner in July of twenty, twenty fifteen. And there's that was that was really what we spent the time talking about. And, you know, because you think about kind of where I was, is that transition from being an academic pursuit to an industrial pursuit. And so a lot of the best people were in these big research labs and that we want to start our own one that, you know, no matter how much resources we could accumulate, would be, you know, pale in comparison to the big tech companies. [00:26:00] And we knew that. And it was a question of are we going to be actually able to get this thing off the ground? You need a critical mass. You can't just do you and a co-founder build the product. [00:26:09] Right. You really need to have a group of, you know, five to 10 people. And we kind of concluded it wasn't obviously impossible. So it seemed worth trying. [00:26:19] Well, you're also a dreamer, so who knows, right? That's right. [00:26:22] OK, so speaking of that, competing with the with the big players, let's talk about some of the some of the tricky things as you think through this process of growing, of seeing how you can develop these systems at a at scale that competes. [00:26:39] So you recently formed OpenAir LP and you cap profit company that now carries the name OpenAir. So open your eyes. [00:26:48] Now, this official company, the original non-profit company, still exists and carries the open air and nonprofit name. So can you explain what this company is, what the purpose of its creation is, and how did you arrive at the decision? Yep. [00:27:05] To create it open I the whole entity and open the LP as a vehicle is trying to accomplish the mission of ensuring that artificial general intelligence benefits everyone. And the main way that we're trying to do that is by actually trying to build general intelligence ourselves and make sure the benefits are distributed to the world. That's the primary way. We're also fine if someone else does this right, it doesn't have to be us. [00:27:27] If someone else is going to build an AGI and make sure that the benefits don't get locked up in one company or, you know, one one, one with one set of people, like, we're actually fine with that. And so those ideas are baked into. [00:27:41] Our charter, which is kind of the the foundational document that, ah, that describes kind of our values and how we operate, but it's also really baked into the structure of open ILP And so the way that we set up opening ILP is that in the case where we succeed, right. [00:27:59] If we actually build what we're trying to build. Then investors are able to get a return and but that return is something that is capped. And so if you think of AIG in terms of the value that you could really create, you're talking about the most transformative technology ever created. It's going to create orders of magnitude more value than any existing company and that all of that value will be owned by the world like legally title to the nonprofit to fulfill that mission. [00:28:26] And so that's that's the structure. [00:28:30] So the mission is a powerful one. And it's it's one that I think most people would agree with. [00:28:36] It's how we would hope A.I. progresses. [00:28:40] And so how do you tie yourself to that mission? [00:28:42] How do you make sure you do not deviate from that mission, that, you know, other incentives that are profit driven, what don't interfere with the mission? [00:28:54] So this is actually a really core question for us for the past couple of years, because, you know, I say that, like, the way that our history went was that for the first year we were getting off the ground. Right. We had this high level picture, but we didn't know exactly how we wanted to accomplish it. And really two years ago, when we first started realizing in order to build ajai, we're just going to need to raise way more money than we can as a nonprofit. [00:29:17] And you are talking many billions of dollars. [00:29:20] And so the first question is, how are you supposed to do that and stay true to this mission? [00:29:25] And we looked at every legal structure out there, and you could have none of them are quite right for what we wanted to do. And I guess it shouldn't be too surprising if you're going to do some, like, crazy, unprecedented technology that you're going have to come up with some crazy, unprecedented structure to do it in. And a lot of a lot of our conversation was with people at opening. I write the people who really joined because they believe so much in this mission and thinking about how do we actually raise the resources to do it and also stay true to to what we stand for. [00:29:53] And the place you've got to start is to really align on what is it that we stand for? What are those values? What's really important to us? And so I'd say that we spent about a year really compiling the opening charter and that that determines and if you even look at the first the first line item in there, it says that, look, we expect we're going to have to marshal huge amounts of resources, but we're going to make sure that we minimize conflicts of interest with the mission. [00:30:15] And that kind of aligning on all of those pieces was the most important step towards figuring out how do we structure a company that can actually raise the resources to do what we need to do. [00:30:27] I imagine open I the decision to create open Alpay was a really difficult one, and there was a lot of discussions, as you mentioned, for a year. And there's different ideas, perhaps detractors within open I sort of different paths that you could have taken. What were those concerns? What were the different paths considered? What was that process of making that decision like? [00:30:52] But so if you look actually at the opening charter that there's almost two paths embedded within it. There is we are primarily trying to build ajai ourselves, but we're also OK if someone else does it. And this is a weird thing for a company. [00:31:06] It's really interesting, actually. Yeah. That there is an element of competition that you do want to be the one that does it. But at the same time, you OK somebody else's. [00:31:16] And we'll talk about that a little bit. That tradeoff, that's the dance. [00:31:19] That's really interesting. And I think this was the core tension as we were designing opening ILP. And really the opening strategy is how do you make sure that both you have a shot at being a primary actor, which really requires building an organization, raising massive resources and really having the will to go and execute on some really, really hard vision. Right. You need to really sign up for a long period to go and take on a lot of pain and a lot of risk. [00:31:44] And to do that, normally you just import the startup mindset. Right. And that you think about, OK, like how do we how to execute everyone? [00:31:51] You have this very competitive angle, but you also have the second angle of saying that, well, the true mission isn't for opening it to build CGI. The true mission is for Ajai to go well for humanity. And so how do you take all of those first actions and make sure you don't close the door on outcomes that would actually be positive and infill the mission? And so I think it's a very delicate balance. Right. And I think that going hundred percent, one direction or the other is clearly not the correct answer. [00:32:18] And so I think that even in terms of just how we talk about opening I and think about it, there's just like like one thing that's always in the back of my mind is to make sure that we're not just saying opening. Eyes goal is to build ajai. Right. That it's actually much broader than that. Right. That first of all, you know, it's not just aget safe ajai that's very important. But secondly, our goal isn't to be the ones to build it. [00:32:40] Our goal is to make sure it goes well for the world. And so I think that figuring out how do you balance all of those and to to get people to really come to the table and compile the the like a single document that that encompasses all of that wasn't trivial. [00:32:54] So part of the challenge here is your mission is, I would say beautiful, empowering and a beacon. [00:33:02] I hope for people in the research community and just people think about I so your decisions are scrutinized more than I think, a regular profit driven company. Do you feel the burden of this in the creation of the charter and just in the way you operate? [00:33:17] Yes. [00:33:20] So why do you lean into the burden by creating such a charter? Why not keep it quiet? [00:33:27] I mean, it just boils down to the to the mission. [00:33:30] Like I'm here and everyone else is here because we think this is the most important mission. I dare to dream. All right. [00:33:36] So what do you think? [00:33:38] You can be good for the world or create an ajai system that's good when you're a for profit company? From my perspective, I don't understand why profit interferes with the positive impact on society. I don't understand why Google makes most of its money from ads. Can't also do good for the world or other companies, Facebook, anything. I don't I don't understand why those have to interfere. You can profit isn't the thing, in my view that affects the impact of a company. [00:34:14] What affects the impact of the company is the charter is the culture, is the you know, the people inside and profit is the thing that just fuels those people. So what are your views there? [00:34:26] Yeah, so I think it's a really good question. And there's there's some some, you know, real like long standing debates in human society that are wrapped up in it. [00:34:33] The way that I think about it is just think about what what are the most impactful nonprofits in the world? What are the most impactful for profits in the world, right? Yes, much easier to list the for profits. That's right. And I think that there's there's some real truth here that the system that we set up, the system for, kind of how, you know, today's world is organized is one that that really allows for huge impact. [00:34:58] And that that kind of part of that is that you need to be that for profits are are self-sustaining and able to to kind of build on their own momentum. And I think that's a really powerful thing. It's something that when it turns out that we haven't set the guardrails correctly, causes problems. Right. Think about logging companies that go into the forest. You know, the rainforest. That's really bad. We don't want that. And it's actually really interesting to me that kind of this this question of how do you get positive benefits out of a for profit company, it's actually very similar to how do you get positive benefits out of an AGI, right. [00:35:33] That you have this, like, very powerful system. It's more powerful than any human and it's kind of autonomous in some ways. You know, it's superhuman and a lot of axes. And somehow you have to set the guardrails to get good things to happen. But when you do, the benefits are massive. And so I think that that when when I think about nonprofit versus for profit, I think it's just not enough happens in nonprofits. They're very pure, but it's just kind of, you know, it's just hard to do things. [00:35:57] They're in for profits in some ways, like too much happens. [00:36:01] But if it kind of shaped in the right way, it can actually be very positive. [00:36:05] And so with our help, we're picking a road in between. Now, the thing I think is really important to recognize is that the way that we think about opening Alpay is that in the world where it actually happens, right. In a world where we are successful, we build the most transformative technology ever, the amount of value we're going to create will be astronomical. Mm hmm. And so then in that case, that the the cap that we have will be a small fraction of the value we create and the amount of value that goes back to investors and employees looks pretty similar to what would happen in a in a pretty successful startup. [00:36:41] And that's really the case that we're optimizing for, right, that we're thinking about in the success case, making sure that the value we create doesn't get locked up. And I expect another, you know, for profit companies that it's possible to do something like that. [00:36:55] I think it's not obvious how to do it right. I think that as a for profit company, you have a lot of fiduciary duty to your shareholders and that there are certain decisions that you just cannot make in our structure. We've set it up so that we have a fiduciary duty to the charter, that we always get to make the decision that is right for the charter rather than even if it comes at the expense of our own stakeholders. And and so I think that when I think about what's really important, it's not really about nonprofit versus for profit. [00:37:23] It's really a question of if you build ajai and you kind of, you know, communities now in this new age, who benefits, whose lives are better. And I think that what's really important is to have an answer that is everyone. Yeah. [00:37:37] Which is one of the core aspects of the charter. [00:37:40] So one concern people have not just with openness, but with Google, Facebook, Amazon, anybody really that that's creating impact at scale is how do we avoid, as your charter says, avoid enabling the use of Ajai to unduly concentrate power? [00:38:00] Why would not a company like open, I keep all the power of any system to itself, the charter, the charter. So how does the charter? Externalise itself in day to day, so I think that the first to zoom out right there, the way that we structure the company so that the power for sort of dictating the actions that opening it takes ultimately rests with the board or the board of the nonprofit. And the board is set up in certain ways, certain certain restrictions that you can read about in the opening ILP blog post. [00:38:33] But effectively, the board is the is the governing body for opening ILP and the board has a duty to fulfill the mission of the nonprofit. And so that's kind of how we tie how we thread all these things together. Now, there's a question of day to day. How do people, the individuals who in some ways are the most empowered ones, you know, the board sort of gets to call the shots at the high level, but the people who are actually executing are the employees or the people here on a day to day basis who have the, you know, the keys to the technical kingdom. [00:39:06] And there I think that the answer looks a lot like, well, how does any company's values get actualized? Right. I think that a lot of that comes down to that. You need people who are here because they really believe in that mission and they believe in the charter and that they are willing to take actions that maybe are worse for them but are better for the charter. And that's something that's really baked into the culture. And honestly, I think it's you know, I think that's one of the things that we really have to work to preserve as time goes on. [00:39:35] And that's a really important part of how we think about hiring people and bringing people into open air. [00:39:40] So there's people here, there's people here who could speak up and say, like, hold on a second, this is totally against what we stand for culture wise. [00:39:51] Yeah, yeah, for sure. I mean, I think that that we actually have I think that's like a pretty important part of of how we operate and how we have even again with designing the charter and designing open Alpay in the first place, that there has been a lot of conversation with employees here and a lot of times where employees said, wait a second, this seems like it's going in the wrong direction and let's talk about it. And so I think one thing that's that's I think a really and, you know, here's here's actually one thing that I think is very unique about us as a small company is that if you're at a massive tech giant, that's a little bit hard for someone who's a line employee to go and talk to the CEO and say, I think that we're doing this wrong. [00:40:28] And, you know, you look at companies like Google that have had some collective action from employees to, you know, make ethical change around things like Mavin. And so maybe there are mechanisms that other companies that work but here are super easy for anyone to pull me aside, to pull Sammis ideology aside and people do it all the time. [00:40:45] One of the interesting things in the charter is this idea that it'd be great if you could try to describe or untangle switching from competition to collaboration. And late stage development was really interesting, this dance between competition and collaboration. How do you think about that? [00:41:00] Yeah, assuming you can actually do the technical side of development. I think there's going to be two key problems with figuring out how do you actually deploy it, make it go? Well, the first one of these is the run up to building the first ajai. You look at how self-driving cars are being developed and it's a competitive race. [00:41:18] And the thing that always happens in a competitive race is that you have huge amounts of pressure to get rid of safety. [00:41:24] And so that's one thing we're very concerned about, right, is that people, multiple teams figuring out we can actually get there. But, you know, if we took the slower path that is more guaranteed to be safe, we will lose. And so we're going to take the fast path. And so the more that we can both ourselves be in a position where we don't generate that competitive race, where we say if the race is being run and that, you know, someone else is further ahead than we are, we're not going to try to to leapfrog. [00:41:52] We're going to actually work with them. We will help them succeed. As long as what they're trying to do is to fulfill our mission, then we're good. We don't have to build it yourselves. And I think that's a really important commitment from us. But it can't just be unilateral. Right. I think it's really important that other players were serious about building ajai, make similar commitments. Right. And I think that that, you know, again, to the extent that everyone believes that aid should be something to benefit everyone, then it actually really shouldn't matter which company builds it. [00:42:19] And we should all be concerned about the case where we just race so hard to get there that something goes wrong. [00:42:24] So what role do you think government, our favorite entity, has in setting policy and rules about this domain, from research to the development to early stage to late stage and energy development? [00:42:40] So I think that, first of all, is really important. The government's in their right in some way, shape or form. You know, at the end of the day, we're talking about building technology that will shape how the world operates and that there needs to be government as part of that answer. And so that's why we've we've done a number of different congressional testimony as we interact with a number of different lawmakers. And, you know, right now, a lot of our message to them is that it's not the time for regulation, it is the time for measurement that our main policy recommendation is that people and, you know, the government does this all the time with bodies like next spend time trying to figure out just where the technology is, how fast it's moving, and can really become literate and up to speed with respect to what to expect. [00:43:30] So I think that today the answer really is about about about measurement. And I think that there will be a time and place where that will change. And I think it's a little bit hard to predict exactly what what exactly that trajectory should look like. [00:43:44] So there will be a point at which regulation federal in the United States, the government steps in and and helps be the I don't want to say the adult in the room to make sure that there is strict rules, maybe conservative rules that nobody can cross. [00:44:02] Well, I think there's there's kind of maybe two two angles to it. So today, with narrow applications that I think there are already existing bodies that are responsible and should be responsible for regulation. You think about, for example, with self-driving cars that you want the you know, the National Highway I. Netzer. Exactly. To be very good. That that makes sense. Right. That basically what we're saying is that we're going to have these technological systems that are going to be performing applications that humans already do great. [00:44:29] We already have ways of thinking about standards and safety for those. So I think actually empowering those regulators today is also pretty important. And then I think for for ajai, you know, that there's going to be a point where we'll have better answers. And I think that maybe a similar approach of first measurement and start thinking about what the rules should be, I think it's really important that we don't prematurely squash, you know, progress. [00:44:53] I think it's very easy to kind of smother the abiding field. And I think that's something to really avoid. But I don't think it's the right way of doing it is to say, let's just try to be ahead and not involve all these other stakeholders. So you've recently released a paper on two language modeling, but did not release the full model because you had concerns about the possible negative effects of the availability of such model. It's outside of just that decision is super interesting because of the discussion as at a societal level. [00:45:32] The discourse it creates is fascinating in that aspect. But if you think about the specifics here at first, what are some negative effects that you envisioned? And, of course, what are some of the positive effects? [00:45:45] Yeah, so again, I think to zoom out like the way that we thought about GP2 is that with language modeling, we are clearly on a trajectory right now where we scale up our models and we get qualitatively better performance. Right to itself was actually just a scale up of a model that we've released in the previous June. Right. We just ran it at a much larger scale and we got these results. We're suddenly starting to write coherent prose, which was not something we'd seen previously. [00:46:17] And what are we doing now? Well, we're going to scale up to by 10x, by 100 X by thousand X, and we don't know what we're going to get. And so it's very clear that the model that we that we released last June, you know, I think it's kind of like it's a good academic to say it's not something that we think is something that can really have negative applications or, you know, to the extent that we can do the positive of people being able to play with it is is, you know, far, far outweighs the possible harms you. [00:46:45] Fast forward to not to, but you 20 and you think about what that's going to be like. And I think that the capabilities are going to be substantive. And so there needs to be a point in between the two where you say this is something where we are drawing the line and that we need to start thinking about the safety aspects. [00:47:05] And I think for too, we could have gone either way. And in fact, when we had conversations internally that we had a bunch of pros and cons and it wasn't clear which one, which one outweighed the other. And I think that when we announced that, hey, we decide not to release this model, then there was a bunch of conversation where various people said, it's so obvious that you should have just released it. There are other people said it's so obvious you should not have released it. [00:47:26] And I think that that almost definitely means that holding it back was the correct decision. Right. If it's if there's if it's not obvious whether something is beneficial or not, you should probably default to caution. And so I think that that the overall landscape for how we think about it is that this decision could have gone either way. There's great arguments in both directions. But for future models down the road and possibly sooner than you'd expect because, you know, scaling these things up doesn't actually take that long. [00:47:52] Those ones you're definitely not going to want to release into the wild. And so I think that we almost feel that this is a test case. [00:47:59] And to see can we even design, you know, how do you have a society where how do you have a system that goes from having no concept of responsible disclosure, where the mere idea of not releasing something for safety reasons is unfamiliar to a world where you say, OK, we have a powerful model, let's at least think about it, let's go through some process and think about the security community. [00:48:19] It took them a long time to design responsible disclosure. You know, you think about this question of, well, I have a security exploit. I send it to the company. The company is like tries to prosecute me or just just ignores it. What do I do? Right. And so, you know, the alternatives of oh, I just just always publish your exploits. That doesn't seem good either. Right. And so it really took a long time and took this this it was bigger than any individual right is really about building a whole community that believe that. [00:48:44] OK, we'll have this process where you sent to the company. You know, if they don't act at a certain time, then you can go public and you're not a bad person. You've done the right thing. And I think that in a high part of the responsibility to just proves that we don't have any concept of this. So that's the high level picture. And so I think that I think this was this was a really important move to make. [00:49:08] And we could have maybe delayed it for TV3. But I'm really glad we did it for you, too. And so now you look contribute to itself and you think about the substance of, OK, what a potential negative applications. So you have this model that's been trained on the Internet, which, you know, it's also going to be a bunch of very biased data, a bunch of, you know, very offensive content in there. And you can ask it to generate content for you on basically any topic. [00:49:31] Right. You just give it a prompt and they'll just start start writing and our content, like you see on the Internet, you know, even down to you like saying advertisement in the middle of some of its generations. [00:49:41] And you think about the possibilities for generating fake news or abusive content. [00:49:46] And, you know, it's interesting seeing what people have done with, you know, we released a smaller version of GP2 and that people have done things like try to generate I, you know, take my own Facebook message history and generate more Facebook messages like me and people generating fake politician content. Or, you know, there's a bunch of things there where you at least have. [00:50:08] To think, is this going to be good for the world? There's the flip side, which is I think that there's a lot of awesome applications that we really want to see, like creative applications in terms of if you have sci fi authors that can work with this tool and come up with cool ideas like that, seems that seems awesome. [00:50:25] If we can write better sci fi through the use of these tools and we've actually had a bunch of people writing to us asking, hey, can we use it for, you know, a variety of different creative applications? [00:50:36] The positive are actually pretty easy to imagine there, if you know the usual and the applications are really interesting. [00:50:46] But let's go there. It's kind of interesting to think about a world where we look at Twitter. [00:50:53] Where they just fake news, but smarter and smarter bots being able to spread it in an interesting, complex networking way in information that just floods out as regular human beings with our original thoughts. [00:51:10] So what are your views of this world? Twenty. Right. [00:51:17] What do you how do we think about again, it's like one of those things about in the 50s trying to describe the the Internet or the smartphone. What do you think about that world, the nature of information? And one possibility is that we'll always try to design systems that identify robot versus human and will do so successfully. And so we will authenticate that we're still human. And the other world is that we just accept the fact that we're swimming in a sea of fake news and just learn to swim there. [00:51:49] Well, have you ever seen the, you know, popular meme of of robot with a physical physical arm and pen clicking? The I'm not a robot button. [00:52:00] Yeah, I think I think the truth is that that really trying to distinguish between robot and human is a losing battle. [00:52:09] Ultimately, you think it's a losing battle? I think it's a losing battle ultimately. Right. I think that that is that in terms of the content, in terms of the actions that you could take, I mean, think about how capturers have gone. Right. The capturers used to be a very nice, simple use of this image. All of our OCR is terrible. You put a couple of of artifacts in it. You know, humans are going to be able to tell what what it is an AI system would be able to do today, like I could barely do. [00:52:31] Captious Yeah. And I think that this is just kind of where we're going, I think captures where we're a moment in time thing. And as A.I. systems become more powerful, that they're being human capabilities that can be measured in the very easy, automated way that the AIS will not be capable of, I think that's just like it's just an increasingly hard technical battle. [00:52:51] But it's not that all hope is lost. Right. [00:52:53] And you think about how do we already authenticate ourselves. Right. You know, we have systems. We have Social Security numbers. If you're in the US or, you know, you have you have, you know, ways of identifying individual people and having real world identity tied to to digital identities seems like a step towards, you know, authenticating the source of content rather than the content itself. Now, there are problems with that. [00:53:17] How can you have privacy and anonymity in a world where the only content you can really trust is we're the only way you can trust content is by looking at where it comes from. And so I think that building out good reputation networks may be maybe one possible solution. But, yeah, I think that this this question is it's not an obvious one. [00:53:34] And I think that we, you know, maybe sooner than we think we'll be in a world where, you know, today I often will read a tweet and be like, I feel like a real human wrote this or do I feel like this is like genuine? I feel like I can kind of judge the content a little bit. [00:53:47] And I think in the future it just won't be the case. You look at, for example, the FCC comments on net neutrality. It came out later that millions of those were auto generated and that the researchers were able to do various statistical techniques to do that. [00:54:01] What do you do in a world where the statistical techniques don't exist? It's just impossible to tell the difference between humans and ice. And in fact, the the the most persuasive arguments are written by by AI, all that stuff. It's not sci fi anymore. You'll get to making a great argument for why recycling is bad for the world. [00:54:19] You got to read that, huh? You're right. [00:54:23] Yeah, that's that's quite interesting. I mean, ultimately, it boils down to the physical world being the last frontier of proving he said, like basically networks of people, humans vouching for humans in the physical world and somehow the authentication ends there. [00:54:40] I mean, if I had to ask you, I mean, you're way too eloquent for a human. So if I had to ask you to authenticate, they prove how do I know you're not a robot and how do you know I'm not a robot? [00:54:52] Yeah, I think that's so far. Where were this in this space, this conversation we just had the physical movements we did is the biggest gap between us and A.I. systems is the physical manipulation. So maybe that's the last frontier. Well, here's another question is, is you know why? [00:55:11] Why is why is solving this problem important? Right. Like what aspects are really important to us? I think that probably where we'll end up is will hone in on what do we really want out of knowing if we're talking to a human. And and I think that, again, this comes down to identity. And so I think that that the Internet of the future, I expect to be one that will have lots of agents out there that will interact with you. [00:55:33] But I think that the question of is this, you know, a real flesh and blood human or is this an automated system? It may actually just be less important. [00:55:43] Let's actually go there. It's too as impressive. And that's a big twenty. Why is it so bad that all my friend. Are GP2 20, why is it so why is it so important on the Internet, do you think, to interact with only human beings? [00:56:04] Why can't we live in a world where ideas can come from models trained on human data? [00:56:10] Yeah, I think this is I think it is actually a really interesting question. This comes back to the how do you even picture a world with some new technology? And I think that that one thing that I think is important is, is, you know, I would say honesty. And I think that if you have, you know, almost the Turing Test style sense sense of of technology, you have eyes that are pretending to be humans and deceiving you. [00:56:31] I think that is you know, that feels like a bad thing. Right? I think that it's really important that we feel like we're in control of our environment. Right. That we understand who we're interacting with and if it's an eye or a human, that that's not something that we're being deceived about. [00:56:45] But I think that the flip side of can I have as meaningful of an interaction with an A.I. as I can with a human? Well, I actually think you can turn to sci fi. And her, I think, is a great example of asking this very question. One thing I really love about her is it really starts out almost by asking how meaningful are human virtual relationships. Right. [00:57:04] And and then you have a human who has a relationship with an AI and that you really start to be drawn into that. Right. That all of your emotional buttons get triggered in the same way as if there was a real human that was on the other side of that phone. [00:57:17] And so I think that this is one way of thinking about it is that I think that we can have meaningful interactions and that if there's a funny joke, sometimes it doesn't really matter if it was written by a human A.I. But what you don't want, and I think we should really draw hard lines is deception. And I think that as long as we're in a world where, you know, why, why do we build A.I. systems at all? Right. [00:57:39] The reason we want to build them is to enhance human lives, to make humans be able to do more things, to have human humans feel more fulfilled. And if we can build AI systems that do that, you know, sign me up. [00:57:50] So the process of language modeling. How far do you think it takes us? [00:57:56] Let's look and move her. Do you think dialogue, natural language, conversation as formulated by the Turing Test, for example, do you think that process could be achieved through this kind of unsupervised language modeling? [00:58:10] So I think the Turing test in its real form isn't just about language. Right? It's really about reasoning. To write that to really pass the Turing test, I should be able to teach calculus to whoever's on the other side and have it really understand calculus and be able to, you know, go in and solve new calculus problems. [00:58:28] And so I think that to really solve the Turing test, we need more than what we're seeing with language models. We need some way of plugging in reasoning. Now, how different will that be from what we already do? That's an open question, right? Might be that we need some sequence of totally radical new ideas, or it might be that we just need to kind of shape our existing systems in a slightly different way. [00:58:50] But I think that in terms of how far our language model will go, it's already gone way further than many people would have expected. Right. I think that things like and I think there's a lot of really interesting angles to poke in terms of how much does to understand physical world like, you know, you read a little bit about fire underwater in in Djibouti, too. So it's like, OK, maybe he doesn't quite understand what these things are. [00:59:12] But at the same time, I think that you also see various things like smoke coming from flame and, you know, a bunch of these things that GBC to it has no body, it has no physical experience. [00:59:22] It's just statically read data. And I think that I think that the answer is like, we don't know yet these questions, though, we're starting to be able to actually ask them to physical systems that the real systems that exist. And that's very exciting. [00:59:37] Do you think what's your intuition? Do you think if you just scale language modeling, like significantly scale, that reasoning can emerge from the same exact mechanisms? [00:59:48] I think it's unlikely that if we just scale GBG to that will have reasoning and the full fledged way. And I think that there is like, you know, the type signatures a little bit wrong. Right? Like there's something we do with that we call thinking right. Where we spend a lot of compute, like a variable amount of compute to get to better answers. Right. I think a little bit harder. I get better answer and that that kind of type signature isn't quite encoded in LGBT. [01:00:15] Right. Will kind of like it's been a long time and it's like evolutionary history making in all this information, getting very, very good at this predictive process. [01:00:24] And then at runtime I just kind of do one forward pass and so and I'm able to generate stuff. And so, you know, there might be small tweaks to what we do in order to get the type signature. Right. For example. Well, you know, it's not really one forward pass, right. You know, you generate some assemble and so maybe you generate like a whole sequence of thoughts and you only keep, like, the last bit or something. [01:00:44] Right. But I think that at the very least, I would expect you have to make changes like that. Yeah. [01:00:49] Yeah. Just exactly how we you said. Think is the process of generating thought by thought in the same kind of way, like you said, keep the last bit the thing that we converge towards. [01:01:01] Yeah, I think there's there's another piece which is which is interesting, which is this out of distribution generalisation. Right. That like thinking somehow that's a do that. Right, that we haven't experienced a thing and yet somehow we just kind of keep refining our mental model of it. This is, again, something that feels tied to whatever reasoning is. [01:01:20] And maybe it's a small tweak to what we do. Maybe it's many ideas and will take us many decades. [01:01:25] Yeah. So the assumption there generalization out of distribution is that it's possible to create new new ideas. [01:01:35] You know, it's possible that nobody's ever created new ideas and then was scaling to did you 20 you would you would essentially generalize to all possible thoughts as he was going to have to just to play devil's advocate. [01:01:52] I mean, how many how many new new story ideas have we come up with? That's Shakespeare, right? [01:01:56] Yeah, exactly. [01:01:58] It's just all different forms of love and drama and so on. OK, not sure if you read, but a lesson. A recent blog post by Sutton. [01:02:07] I have. [01:02:08] He basically says something that echoes some of the ideas that you've been talking about, which is, he says the biggest lesson that can be read from 70 years of research is that general methods of leverage computation are ultimately going to ultimately win out. Do you agree with this basically of and open in general about the ideas you're exploring, about coming up with methods? Well, there's tippity to modeling or whether it's open air five playing Dota or a general method is better than the more fine tuned expert tuned. [01:02:46] Method. Yeah, so I think that well, one thing that I think was really interesting about the reaction to that blog post was that a lot of people have read this as saying that compute is all that matters and it's a very threatening idea. Right. And I don't think it's a true idea either. It's very clear that we have algorithmic ideas that have been very important for making progress and to really build ajai. You want to push as far as you can on the computational scale and you want to push as far as you can on human human ingenuity. [01:03:12] And so I think you need both. But I think the way that you phrased the question is actually very good, right. That it's really about what kind of ideas should we be striving for. And absolutely, if you can find a scalable idea for more computing to put more data into it, it gets better like that. That's the real Holy Grail. [01:03:31] And so I think that the answer to the question, I think is yes, that that that's really how we think about it. And that part of why we're excited about the power of deep learning, the potential for building ajai is because we look at the systems that exist in the most successful AI systems and we realize that you scale those up, they're going to work better. And I think that that scalability is something that really gives us hope for being able to build transformative systems. [01:03:56] So I'll tell you, this is partially an emotional you know, I think that response that people often have as computers so important for state of the art performance, you know, individual developers, maybe a 13 year old sitting somewhere in Kansas or something like that. You know, they're sitting they might not even have a GPU and or maybe have a single GPU or ten eighty or something like that. [01:04:17] And there's this feeling like, well, how can I possibly compete or contribute to this world of I if scale so important. [01:04:27] So if you can comment on that and in general, do you think we need to also in the future focus on democratizing compute resources more, more or as much as we democratize the algorithms? [01:04:39] Also, the way that I think about it is that there's the space of of possible progress. There's a space of ideas and sort of systems that will work, that will move us forward. And there's a portion of that space and to some extent increasingly significant portion of that space that does just require massive compute resources. [01:04:58] And for that that I think that the answer is kind of clear, that part of why we have the structure that we do is because we think it's really important to be pushing the scale and to be, you know, building as large clusters and systems. [01:05:11] But there's another portion of the space that isn't about the large scale compute that these ideas that and again, I think that for the ideas to really be impactful and really shine who they should be, ideas that if you scale them up, would work way better than they do at small scale, but you can discover them without massive computational resources. And if you look at the history of of recent developments, you think about things like the gown or the VA, that these are ones that I think you could come up with them without having. [01:05:39] And, you know, in practice, people did come up with them without having massive, massive computational resources. I just talked to a good fellow. [01:05:45] But the thing is, the initial Gane produced pretty terrible results. Right? [01:05:51] So only because it wasn't a very specific it was only because they're smart enough to know that this is quite surprising in general, anything that they know. Do you see a world or is that too optimistic? And Dreamer like to imagine that the compute resources are something that's owned by governments and provided as utility? [01:06:12] Actually, to some extent, this this question reminds me of of blog posts from one of my former professors at Harvard, this guy, Matt, Matt Welsh, who is a systems professor. I remember sitting in his tenure talk. Right. And you know that he had literally just gotten tenure. He went to Google for the summer and then decided he wasn't going back to academia. Right. And that kind of in his blog post, he makes this point that, look, as a systems researcher, that I come to these cool system ideas. [01:06:40] Right. And kind of a little proof of concept. And the best thing I could hope for is that the people at Google or Yahoo! [01:06:47] Which was around at the time, will implement it and actually make it work at scale. Right. That's like the dream for me, right? I built the little thing and they the big thing that's actually working. [01:06:57] And for him, he said, I'm done with that. I want to be the person who's who's actually doing the building and deploying. And I think that there's a similar dichotomy here. Right? I think that there are people who really actually find value. And I think it is a valuable thing to do to be the person who produces those ideas. Right. Who build the proof of concept. [01:07:16] And yeah, you don't get to generate the coolest possible Gane images, but you invented the gane. Right. And so that there's there's there's a real tradeoff there. And I think that's a very personal choice. But I think there's value in both sides. [01:07:28] So do you think creating ajai something or some new models would we would see echoes of the brilliance even at the prototype level, so you would be able to develop those ideas without scale, the initial sew seeds. [01:07:44] So to take a. And, you know, I always like to look at the examples that exist, right, look at real precedent. And so take a look at the June twenty eighteen model that we released that we scaled up to turn to. And you can see that at Smallscale, it set some records. This was the original Deepti. We actually had some some cool generations that weren't nearly as amazing and really stunning as the two ones. But it was promising. [01:08:09] It was interesting. And so I think it is the case that with a lot of these ideas that you see promise that small scale. But there is an asterisk here, a very big asterisk, which is sometimes we see. Behaviors that emerge that are qualitatively different from anything we saw at small scale and that the original inventor of whatever algorithm looks at and says, I didn't think I could do that. This is what we saw in Dota. Right. [01:08:34] So Pippo was was created by John Coleman, who's a researcher here. And and with with Doda. We basically just ran a at massive, massive scale and some tweaks in our store in order to make it work. [01:08:46] But fundamentally it's p0 at the core. [01:08:48] And we were able to get this long term planning, these these behaviors to really play out on a time scale that we just thought was not possible. [01:08:58] And John looked at that and was like, I didn't think it could do that. That's what happens when you get three orders of magnitude more scale tested at. [01:09:05] Yeah, but it still has the same flavors of, you know, at least echoes of the expected billions, although I suspect with Deepti is scaled more and more, you might get surprising things. So, yeah, you're right. It's interesting that it's it is difficult to see how far an idea will go when it's scaled. [01:09:26] It's an open question also to that point with with Dota and people like I mean, here's here's a very concrete one, right? It's like it's actually one thing it's very surprising about Dota, but I think people don't really pay that much attention to is the degree of generalization our distribution that happens. [01:09:41] Right, that you have this A.I. that's trained against other bots for its entirety, the entirety of existence, decided to take a step back and you can't talk through it. [01:09:51] You know, a story of Dota, a story of leading up to open five and that passed. And what was the process of self playing. So out of training. Yeah, yeah. [01:10:03] Yeah. So so with his daughter Dota, it's a complex video game. And we started training. We started trying to solve Dota because we felt like this was a step towards the real world relative to other games like chess or go. Right. Those very cerebral games where you just kind of have this bored, very discrete moves. [01:10:19] Dota starts to be much more continuous time that you have this huge variety of different actions, that you have a 45 minute game with all these different units. And it's got a lot of messiness to it that really hasn't been captured by previous games. And famously, all of the hardcoded bots for Dota were terrible. [01:10:35] It's just impossible to write anything good for it because it's so complex. And so this seemed like a really good place to push what's the state of the art in reinforcement learning? And so we started by focusing on the one versus one version of the game. And and we're able to to solve that. We're able to beat the world champions. And that the that the learning, you know, the skill curve was this crazy exponential. Right. It was like constantly we were just scaling up that we were fixing bugs. [01:10:59] And, you know, that you look at the at the skill curve and it was really very, very smooth. One was actually really interesting to see how that, like, human iteration loop yielded very steady, exponential progress. [01:11:09] And to one side note, first of all, it's an exceptionally popular video game. The side effect is that there's a lot of incredible human experts at that video. Again, so the benchmark that you're trying to reach is very high. And the other can you talk about the approach that was used initially and throughout the training, these agents to play this game? [01:11:29] Yep. And so the approach that we used is self play. And so you have two agents that don't know anything. They battle each other. They discover something a little bit good, and now they both know it and they just get better and better and better without bound. [01:11:41] And that's a really powerful idea, right, that we then went from the one versus one version of the game and scaled up to four versus five. Right. So you think about kind of like with basketball, where you have this, like, team sport and you need to do all this coordination. And we were able to push the same idea, the same self play to to really get to the professional level at the full five versus five version of the game. [01:12:06] And and the things I think are really interesting here is that these agents, in some ways, they're almost like an insect like intelligence, right. Where, you know, they have a lot in common with how an insect is trained. Right. Insect kind of lives in this environment for very long time. You know, the answer to this insect, I've been around for a long time and had a lot of experience that gets baked into into into this agent. [01:12:27] And, you know, it's not really smart in the sense of a human right. It's not able to go in, learn calculus, but it's able to navigate its environment extremely well and able to handle unexpected things in the environment that's never seen before pretty well. And we see the same sort of thing with our Doda bots. Right? They're able to within this game, they're able to play against humans, which is something that never existed in its evolutionary environment, totally different play styles from humans versus the bots, and yet it's able to handle extremely well. [01:12:54] And that's something that I think was very surprising to us, was something that doesn't really emerge from what we've seen with Pippo at smaller scale, the kind of scale we're running, the stuff that was so, you know, I could take one hundred thousand CPU cores running with like hundreds of DPAs is probably about, you know, like, you know, something like hundreds of of years of experience going into this bot every single real day. And so that scale is massive and we start to see very different kinds of behaviors out of the algorithms that we all know and love. [01:13:28] You mentioned beat the world expert one by one, and then you didn't weren't able to win five five this year. [01:13:38] Yeah. At the best players in the world. So what's what's the comeback story? What's first of all, talk through that does exceptionally exciting event and what's what's the following months and this year look like. [01:13:50] Yeah. Yeah. [01:13:51] So well, one thing that's interesting is that, you know, we lose all the time, right. Because we because we so the Dota team at opening night, we played the bot against better players than our system all the time. Or at least we used to write like, you know, the first time we lost publicly was we went up on stage at the International and we played against some of the best teams in the world. And we ended up losing both games. [01:14:13] But we gave them a run for their money. Right. The both games were kind of 30 minutes. Twenty five minutes. And they went back and forth, back and forth, back and forth. And so I think that really shows that we're at the professional level. And that kind of looking at those games, we think that the queen could have gone a different direction and we could have could have had some wins. That was actually very encouraging for us. [01:14:33] And, you know, it's interesting because the international was at a fixed time. Right? So we knew exactly what day we were going to be playing and we pushed as far as we could as fast as we could. Two weeks later, we had about that had an 80 percent win rate versus the one that played at T'ai. So the march of progress, you know, you should think of as a snapshot rather than as an end state. And so, in fact, Will will be announcing our our finals pretty soon. [01:14:56] I actually think that we'll announce our final match prior to this podcast being released. [01:15:02] So there should be we'll be playing or playing against the the world champions. And, you know, for us, it's really less about like that. The way that we think about what's upcoming is the final milestone, the final competitive milestone for the project. [01:15:17] Right. That our goal in all of this isn't really about beating humans at Dota. Our goal is to push the state of the art and reinforcement learning. And we've done that right. And we've actually learned a lot from our system. And that we have, you know, I think a lot of exciting next steps that we want to take. And so a final showcase of what we built. We're going to do this match. But for us, it's not really the success or failure to see, you know, do do we have the clean up go in our direction or against. [01:15:43] Where do you see the field of deep learning heading in the next few years? What do you see the work and reinforcement learning, perhaps hiding and. [01:15:56] More specifically, with Open Eye, all the exciting projects that you're working on. What is 12 19 hold for the massive scale scale? [01:16:05] I will put an asterisk on that and just say, you know, I think that it's about eight years plus scale. You need both. [01:16:10] So that's a really good point. So the question in terms of ideas, you have a lot of projects that are exploring different areas of intelligence. And the question is, when you when you think of scale, do you think about growing the scale of those individual projects or do you think about adding new projects and solitude? [01:16:32] If you are thinking of adding new projects or if you look at the past, what's the process of coming up with new projects, new ideas, you know? [01:16:40] So we really have a lifecycle of project here. So we start with a few people just working on a small scale idea. And language is actually a very good example of this. That is really, you know, one person here who was pushing on language for a long time. I mean, then you get signs of life. Right? And so this is like let's say, you know, with with the original GBG, we had something that was interesting and we said, OK, it's time to scale this right. [01:17:02] It's time to put more people on it, put more computational resources behind it. And and then we just kind of keep pushing and keep pushing at the end state is something that looks like Dota or robotics, where you have a large team of, you know, 10 or 15 people that are running things at very large scale and that you're able to really have material engineering and and and, you know, sort of machine learning science coming together to make systems that work and get material results that just would have been impossible otherwise. [01:17:29] So we do that whole life cycle. We've done a number of times, you know, typically end to end, probably to two years or so to do it. You know, the organization's been around for three years or so. Maybe we'll find that we also have longer lifecycle projects, but we work up to those we have. [01:17:46] So so one one team that we were actually just starting, Éliane, I are kicking off a new team called the Reasoning Team, and that this is to really try to tackle how do you get neural networks to reason. And we think that this will be a long term project and one that we're very excited about in terms of reasoning. [01:18:03] Super exciting topic. What do you what kind of benchmarks, what kind of tests of reasoning do you envision what would if you said back, whatever drink and you would be impressed that the system is able to do something, what would that look like? They're improving. They're improving. [01:18:23] So some kind of logic and especially mathematical logic. [01:18:27] I think so. Right. And I think that there's there's there's kind of other problems that are dual to think improving in particular. [01:18:33] You know, you think about programming. I think about even like security analysis of code that these all kind of capture the same sorts of core reasoning and being able to do some out of distribution generalization. It would be quite exciting if OpenAir reasoning team was able to prove that P equals NP would be very nice. [01:18:53] It would be very, very exciting, especially if it turns out the pig will then be. That'll be interesting, too. [01:18:58] Maybe just it would be ironic and humorous. [01:19:04] Uh, so what problem stands out to you as the most exciting and challenging, impactful to the work for us as a community in general and for open eye this year? He mentioned reasoning. I think that's that's a heck of a problem. Yeah. [01:19:18] So I think reasoning is an important one. I think it's going to be hard to get good results in twenty nineteen. You know, again, just like we think about the life cycle takes time I think for twenty nineteen language modeling seems to be kind of on that ramp. Right. [01:19:29] It's at the point that we have a technique that works. We want to scale one hundred thousand actually. What happens. Awesome. [01:19:36] Do you think we're living in a simulation. [01:19:39] I think it's I think it's hard to have a real opinion about it. You know, it's actually interesting. I separate out things that I think can have like, you know, yield materially different predictions about the world from ones that are just kind of, you know, fun to speculate about. And I kind of view simulation. It's more like, is there a flying teapot between Mars and Jupiter? Like, maybe, but it's a little bit hard to know what that would mean for my life. [01:20:02] So there is something actionable. So some of the best work opening has done is in the field of reinforcement learning and some of the success of reinforcement learning come from being able to simulate the problem and trying to solve. [01:20:17] So do you have a hope for reinforcement for the future, reinforcement learning and for the future of simulation, like what we're talking about autonomous vehicles or any kind of system. Do you see that scaling up or will it be able to simulate systems and hence be able to create a simulator that echoes our real world and proving once and for all, even though you're denying it, that we're living in a simulation? [01:20:42] It seems that for questions. Right. So, you know, kind of at the core there of like, can we use simulation for self driving cars? [01:20:48] Take a look at our robotic system. Dactyl, right. That was trained in simulation using the Doda system, in fact. And it transfers to a physical robot. And I think everyone looks at our data system, OK, it's just a game. How are you ever going to escape to the real world? And the answer is, well, we did it with the physical robot that no one can program. And so I think the answer, a simulation goes a lot further than you think if you apply the right techniques to it. [01:21:11] Now, there's a question of, you know, ah, the being in that simulation going to going to wake up and have consciousness. I think that one seems a lot harder to take and reason about. [01:21:20] I think that, you know, you really should think about like where where exactly does human consciousness come from and our own self awareness. [01:21:26] And, you know, is it just that, like, once you have like a complicated enough neural net, you have to worry about the agents feeling pain. And, you know, I think there's like interesting speculation to do there. But but, you know, again, I think it's a little bit hard to know for sure. [01:21:40] Let me just keep the speculation, do you think, to create intelligence, general intelligence, you need one consciousness and two a body. Do you think any of those elements are needed or is intelligence something that's that's orthogonal to those? [01:21:55] I'll stick to the kind of like the non grand answer first. Right. [01:21:59] So the non grand answer is just to look at, you know, what are we already making work you'll get to? A lot of people would have said that even get these kinds of results. You need real world experience. You need a body, you need grounding. How are you supposed to reason about any of these things? How are you supposed to, like, even kind of know about smoke and fire and those things? If you've never experienced them and you do shows that you can actually go way further than that kind of reasoning would predict? [01:22:24] So I think that in terms of do need conscience, do we need a body, it seems the answer is probably not right, that we probably just continue to push kind of the systems we have. They already feel, general, they're not as competent or as general or able to learn as quickly as an ajai would. But, you know, there are at least like kind of Proteau ajai in some way, and they don't need any of those things now. [01:22:47] Now, let's move to the grand answer, which is, you know, if our neural net nets conscious already, would we ever know? How can we tell? [01:22:55] Right. Yeah. Here, here's where the speculation starts to become become, you know, at least interesting or fun and maybe a little bit disturbing, depending on where you take it. But it certainly seems that when we think about animals that there's some continuum of consciousness. You know, my cat, I think is is conscious in some way. Right. You know, not as conscious as a human. And you could imagine that you could build a little consciousness metre. [01:23:18] Right. You point a cat, gives you a little breathing point and assuming and gives you a much bigger reading. [01:23:23] What would happen if you point to one of those at a the neural net? And if you're training this massive simulation, do the neural nets feel pain? [01:23:32] You know, it becomes pretty hard to know that the answer is no and it becomes pretty hard to to really think about what that would mean if the answer were yes. [01:23:42] And it's very possible. You know, for example, you could imagine that maybe the reason that humans are have consciousness is because it's a it's a convenient computational shortcut. Right. If you think about it, if you have a being that wants to avoid pain, which seems pretty important to survive in this environment and wants to like, you know, eat food, then that may be the best way of doing it is to have a being that's conscious. Right. [01:24:04] That, you know, in order to succeed in the environment, you need to have those properties and how are you supposed to implement them? And maybe this this consciousness is a way of doing that. If that's true, then actually maybe we should expect that really competent reinforcement learning agents will also have consciousness. [01:24:19] But, you know, that's a big if. And I think there are a lot of other arguments that can make another directions. [01:24:24] I think it's a really interesting idea that even GP2 has some degree of consciousness, that something is actually not as crazy to think of, as useful to think about, as as we think about what it means to create intelligence of a dog, intelligence of the cat and the intelligence of human. So last question, do you think. We will ever fall in love, like in the movie her with an artificial intelligence system or an artificial intelligence system falling in love with a human. [01:24:55] I hope so. If there's any better way to end, it is on love. So Greg, thanks so much for talking to me. Thank you for having me.
