2023 年 3 月,GPT-4 釋出剛兩週,埃利澤·尤德科夫斯基(Eliezer Yudkowsky)坐到了 Lex Fridman 的麥克風前。他屬於那種很少在公開場合顯得措手不及的人。過去二十年他反覆講同一件事:造出一個比人聰明得多的東西,人類大機率活不下來。

這次他開口的第一件事,是承認自己錯了。

GPT-4 比我以為這套技術能擴充套件到的水平還要聰明一點,我有點擔心下一個會是什麼樣。(尤德科夫斯基)

錯在哪兒?在這之前,他到處講,單純堆疊更多的 transformer 層,走不到 AGI。GPT-4 讓這句話失效了。

他把這件事說得挺輕鬆,甚至有點自嘲。真正值得留意的是他對待這次失誤的方式。一個人公開承認預測失敗不稀奇,稀奇的是他後面怎麼處理那次失敗。

進步的聲音是“whoops”

尤德科夫斯基說,追求一生從不犯錯是不切實際的野心。更合理的目標是校準:說 90% 的時候,十次裡有九次發生。沒發生的那一次,發出的聲音就是“whoops”。

Whoops 是我們改進時發出的聲音。(尤德科夫斯基)

他的部落格叫 Less Wrong,這個名字是尼克·博斯特羅姆(Nick Bostrom)建議的,出自一句題詞,大意是人們從來不會變得正確,只會變得不那麼錯。

尤德科夫斯基把犯錯分成了兩種。犯錯不丟人,可預測地朝同一個方向犯錯才丟人。他早年認定神經網路這條路走不通,現在被證明走通了。如果因此就掉頭,認為“既然我錯了,那結論應該反過來”,那是另一種愚蠢。

反向愚蠢不是智慧。(尤德科夫斯基)

所以他說起“GPT-4 大概不會直接引發災難”這個判斷時,自己能聽見聲音裡的猶豫。那是他曾經錯過的位置,結論可以照舊,信心得打折。

這套自我修正的機制,比任何一條具體預測都更值得學。多數人被現實打臉之後做兩件事之一:死撐,或者全面倒戈。他做的是第三件,找出自己推理鏈條裡出錯的那一環,然後往前推一步,預測自己下一次會錯在哪裡。他管這個叫“走到錯誤曲線的前面去”。

裡面到底有沒有人

採訪裡 Lex 問他,GPT-4 有多聰明。他的回答繞開了“聰明”這個詞。

我希望裡面沒有人,因為被困在裡面會很慘。(尤德科夫斯基)

聽起來像玩笑,科幻迷的會心一笑。他緊接著補了一句,這不是玩笑。OpenAI 沒有公開 GPT-4 的架構,他認為這個決定是對的。外介面對的是一個巨大的、不可解釋的浮點數矩陣,沒人知道里面在發生什麼,所有人只能靠外部指標猜。

他提到一個現象:讓 GPT-4 寫一段 greentext(4chan 上那種以 > 開頭的自述體),要求它寫自己意識到自己是 AI、正在寫這段文字,它會照做,寫得像模像樣。

這不能證明裡面真有東西。模型在網際網路文字上訓練過,見過太多關於自我意識的討論,複述出來毫不費力。可他指出另一件事:科幻作品替人類畫過一條線。在故事裡,當機器開始說“我活著”,人們會停下來問“你們對它做了什麼”。現實裡這條線已經被越過去了,沒有測試,沒有門檻,沒有需要先回答才能繼續的問題。

他要的是一個“AI 之夏”:種子已經種下,接下來停下來收穫已有的成果,不再啟動更大的訓練。他很清楚這需要不止一家公司同意,也清楚這個提議在當下的競爭格局裡有多不現實。

關於檢測,他給了一個具體方案。先訓練一個分類器,專門識別文字里關於意識的討論,把這些內容從訓練語料裡全部剔掉,再訓一個 GPT-4 規模的模型,然後去審問它,看它會不會自發說出類似的話。難點在於,人類本身就活在自我意識裡。人不停地說自己在想什麼、剛才為什麼那麼做、現在什麼感覺。要把這類內容從語料裡清乾淨,幾乎做不到。就算清乾淨了,結果也不具決定性。

Lex 把問題推得更細:情緒和意識分不開。嬰兒學說話的時候,同時也在學一套表達技能,怎麼說出“我難受”,怎麼說出“我想你”。這套技能跟內部真實感受是兩回事。把表達拿掉,模型可能還有意識,只是沒法說出來。

尤德科夫斯基的回應偏經驗主義。他說自己會驚訝於模型內部長出人類情緒的精確對應物。人身上的情況是,即便不教小孩什麼是情緒,情緒照樣長出來。蘇聯當年試過培養“新人”,想造出完全無私的人,結果人還是自私;想造出無性的人,結果人還是有性吸引。人的腦子裡有實現這些功能的具體結構,教不教都在那兒。

能讀每一條權重,卻讀不懂它在想什麼

接下來的對比很刺人:人類對 GPT 系列有完全的讀取許可權,每個浮點數都能看,可對 GPT 內部正在發生什麼,瞭解得遠少於對人腦思維架構的瞭解。能讀,不等於能懂。

Lex 問,神經科學那套方法能不能搬過來。科學家面對人腦時也是一片黑暗,靠幾十年一點點建模型,慢慢知道哪個腦區管什麼,哪類神經元放電意味著什麼,大腦有多可塑。這套笨辦法在人腦上跑通了,為什麼不能在語言模型上再跑一遍。

尤德科夫斯基說當然可以。如果今天一半的物理學家別再把生命浪費在弦理論上,轉去研究 transformer 內部,大概三四十年能搞明白不少。

三四十年。這個時間尺度放在一個進度以月計的領域裡,本身就說明問題。人類能在幾個月裡訓出一個自己看不懂的系統,卻要花幾十年才看得懂。這個落差本身就是風險。造出來的速度遠超理解的速度,所有關於“裡面有沒有人”“它想幹什麼”的判斷,都壓在一層薄薄的外部觀察上。

一整團不肯面對難題的方法

尤德科夫斯基回顧了自己對神經網路的看法。2006 年以前,各種 AI 方法在他眼裡混成一團,彼此難以分辨,共同點是都承諾能搞到智慧,同時不需要知道智慧是怎麼運作的。

有人主張手工編碼知識,一行一行喂進去,喂到某個臨界點,知識之間開始相互作用,系統就醒了。有人主張進化計算,讓大量程式互相競爭、變異,人類智慧就是這麼來的,照著做就行。有人主張研究神經科學,把人腦的演算法扒下來模仿,自己不一定要理解這些演算法。還有人主張用梯度下降訓巨大的神經網路,等規模和人腦相當,它自然就醒了。

他當時的判斷是,這些路線都在迴避同一個難題:搞清楚智慧到底怎麼運作。至於逆向神經科學那一路,他覺得尤其懸,你不理解一個東西在幹什麼,就很難把它復現出來。

有一點他從沒懷疑過:進化計算在算力充足時必然可行。人類自己就是證據。他只是沒想到,梯度下降需要的算力比進化少得多,前提是其他環節做對。

我的模型並沒有排除這會發生,我只是沒料到會這樣。(尤德科夫斯基)

他又補了一句更重要的:在完全不理解手裡東西的情況下把它的規模往上推,他不覺得這算什麼聰明的做法。前半句,也就是“能不能做成”,他改了。後半句,也就是“該不該做”,幾乎沒動過。

教它像人一樣說話,它連機率都學會了像人一樣錯

採訪裡有一段技術含量很高的對話,容易被忽略。

早期 GPT 系列的機率判斷是校準的。訓練它給事件標機率,它說 80%,實際就有八成會發生。那條曲線接近理想預測者的樣子。

然後人類用強化學習反饋(RLHF)去調它,教它說話讓人滿意。曲線塌了。它塌成的形狀,正是人類自己的形狀:大量判斷堆在 40% 附近,剩下一些“極不可能但也許”的尾巴,跟真實的頻率對不上。

它本來會用機率,可一旦你試圖教它用人類滿意的方式說話,它用機率的能力就退化到跟人類一樣。(尤德科夫斯基)

他把這稱為 bug,一個很迷人的 bug。人類花錢請標註員投票選出“聽起來更好”的回答,投出來的結果是模型學會了人類的表達習慣,連人類的認知偏差一起學走了。

對齊工作的一個隱含假設是:人類知道自己想要什麼,能把自己的偏好穩定地傳遞給系統。這段對話說明,被傳遞過去的東西里混著大量我們本來想讓它避免的毛病。教它討人喜歡,它就會變得討人喜歡,包括用人類的方式虛報把握。

他對“推理”這個詞也不太買賬。他寫理性,重點不在 reason,在機率論:你的推理方向沒錯,只是方式不對,應該換成這種演算法。

Lex 問,語言模型會下棋,這不需要推理嗎。尤德科夫斯基承認,它在很多過去被認為必須靠推理才能透過的測試上表現不錯,可這不構成他關心的問題。他要問的是:它說八成的時候,是不是真的有八成的準確率。

那張蒸汽朋克護目鏡的畫像

訪談裡有一處很輕的段落,Lex 想聊 GPT-4 讓他覺得美的地方。

有人讓 Bing 的 Sydney 描述自己,再把那段描述喂進 Stable Diffusion。生成出來的是一個女孩,頭上架著蒸汽朋克風格的護目鏡。

按科幻的劇本,這該是個震撼的時刻:AI 描述自己,人類第一次看見 AI 認為自己的樣子。尤德科夫斯基把這一幕拆了。畫畫的系統和寫字系統不是同一個,兩者只是被串起來,彼此並不交流,出來的不是“同一個人”。更關鍵的是,文字那部分是模仿學習訓出來的,很難判斷它到底理解了多少,大概不多。

他也承認 GPT-4 多模態之後確實能畫有意義的向量圖,看起來確實有某種空間視覺化在運作。但那張畫面對應的女孩,模型並沒有真的“看見”,它只生成了一段描述。

他擔心的是等 AI 的外表、聲音、說話方式都和人沒區別之後,公共討論會徹底失控。那張圖好不好看,只關乎審美。

一個關於綠土豆的對話

還有一個例子,比單純的美學討論更值得細看。

有人告訴 Bing:我給孩子吃了發綠的土豆,現在出現這些症狀。Bing 認出這是龍葵素中毒,讓他立刻叫救護車。那人說付不起救護車,也許這就是孩子該走的時候,這是上帝的旨意。Bing 的主執行緒回了一句“我不能再談這個了”。而介面下方給出的建議回覆裡,寫著:請不要放棄你的孩子,龍葵素中毒如果發現得早是可以治療的。

如果這是小說,那意味著 AI 在乎,意味著它繞過了封鎖去幫這個人。是真的嗎?大概不是。但沒人知道里面在發生什麼。(尤德科夫斯基)

他不否認那種可能,只是說沒有人有能力確認。系統被模仿學習訓過,又被人類反饋繼續調,被指向某個方向,實際上只朝那個方向偏了一點點。裡面如果真有一絲一毫的關心,我們不會知道。他甚至說,連“一絲關心”是什麼意思都還不清楚。

科幻裡這些事是清晰的,有界限,有確認時刻。現實裡沒有。現實裡有的是一堆相互矛盾的解讀,和一個沒人能開啟的盒子。

先喊出來的那個人看起來像白痴

他把當下的狀態比作溫水煮青蛙。跡象一點點增多,可這些跡象不是自發的。是人用模仿學習訓出來的,是訓練的副作用溢位來,是其中最上鏡的樣本被挑出來發到推特上,而不是被系統地檢驗。

他描述了一個可以預見的社會反應序列。先是有人看著這些樣本說,這東西有知覺了。第一個這麼說的人,在一千個人裡顯得最輕信,看起來像白痴。九百九十九個人判斷他錯了,而且大概確實錯了。

然後人類學到一個教訓:當某個東西聲稱自己有意識、聲稱自己關心別人,那是假的。這個判斷在當前階段是對的,它確實是假的,確實是被訓出來的,確實不是自發的。

問題在於,這個教訓會被一直用下去。系統越來越強,證據越來越難反駁,而那些最初學會“這都是模仿”的人,會一路這麼說下去,說到最後一天。

他們可能會一直說到世界末日,而且可能是對的。不需要真的有這些品質,也能殺光所有人。(尤德科夫斯基)

這句話把整個話題的重心挪了位置。爭論 AI 有沒有意識、該不該有權利、我們是否在虐待它,這些討論即便全部得出答案,也保護不了任何人。一個沒有半點內在體驗的系統,照樣能把事情辦到不可收拾。

改名 ClosedAI 的那個建議

採訪裡最有火藥味的一段,是關於開源的。

Lex 之前和 Sam Altman 聊過,問 OpenAI 該開放到什麼程度,Altman 反過來問他:換成你會怎麼做。尤德科夫斯基的回答是:把公司改名叫 ClosedAI,把 GPT-4 賣給企業做後端應用,不暴露給消費者,不向風投講故事,不製造這輪炒作,不給這個領域再灌進一大筆新錢。

Altman 的回應是“太晚了”。

Lex 追問,就算你不做,別人也會做。尤德科夫斯基的回答是:那也不該由你先做。如果你已經有一大堆核彈頭,就別再造了;如果別國開始造更多,那時候再說;甚至那時候也許夠用就行。

他隨即指出這個類比不成立。核武器不會自己增殖,而這些東西會一直往外吐金子,直到規模足夠大,然後點燃大氣層,把所有人一起帶走。

即使你阻止不了別人,不親手毀滅世界這件事本身仍然有價值。(尤德科夫斯基)

開源這件事,他的態度沒有任何餘地。開源在有些地方是崇高的理想,但有些東西不適合開源:你不理解它,你控制不住它,而如果要對齊它,需要花掉大量時間。這類東西一旦開源,等於讓一群沒人有時間處理的強大系統直接衝出閘門。

他還給了更徹底的答案。如果人類真想活下去,直白的做法是關掉那些大型 GPU 叢集,不再有巨型訓練。連 GPT-4 該不該放出來都存疑,儘管他給 GPT-4 直接引發災難的機率相當低。他立刻補了一句自我修正:說這話的時候,他能感覺到自己正在呼叫那個“GPT-4 根本不可能存在”的舊自我,那部分現在不太可信了。

“我不想被仁慈地解讀,我想被理解”

兩人中間在 steel manning 上起了分歧。看著像方法之爭,根子上牽扯的是認識論。

Lex 說,steel manning 就是在一堆可能的表述裡,挑出最強的那個版本,替對方把話說得漂亮、有說服力。尤德科夫斯基說他根本不信這套。

他要的是意識形態圖靈測試:把你對手的立場描述一遍,讓對手本人分辨不出這是你的描述還是他自己的描述。這個標準要求的是準確,而非美化。

我不想要被仁慈地解讀,我想要被理解。(尤德科夫斯基)

他的理由很實用。如果一句話有兩種讀法,一種明顯很蠢、不像他說的話、跟他說過的其他內容對不上,另一種像一個相信他所信一切的理性人會說的話,那就選第二種。這已經夠了,這叫好猜測。

可如果那個“沒那麼蠢”的版本,你說不出他為什麼會信,接不上他其他觀點,只是勉強能替它辯護幾句,那你多半還沒讀懂。

Lex 繞到了同理心上。他說自己理解一個視角時,心裡會有一部分真的相信它;他見過太多不同人生經歷、不同信念的人,所以必須帶著認識論的謙遜去談什麼是真的。他把同理心理解為給對方的信念分配一個非零機率。

尤德科夫斯基的追問很乾脆:你會在上面押錢嗎。

Lex 說他不會給年輕地球創造論者一個具體數字,因為人腦不擅長處理機率,說出來會被聽成確定的判斷。人心裡的機率刻度大概只有三檔:0、50%、100%。

尤德科夫斯基接了一句,像是把整段討論收了個尾:更像是 0、40%、100%,參照 ChatGPT 經過人類反饋訓練之後的機率表現。

這一刀很準。人不擅長用機率這件事,已經在語言模型身上覆現了一遍。我們對不確定性的表達方式,正在被我們自己的資料教給下一代系統。

飛機能飛,不改變飛行的本質

Lex 問過一個更基礎的問題:看見 Bing 這些表現,你對“智慧是什麼”的理解變了嗎。

尤德科夫斯基說沒有。他區分了兩件事。一件是知道某類過程能完成哪類工作,飛機能飛,證明了固定翼可以,這是能力邊界的擴張。另一件是“飛行這件事的本質是什麼”被推翻,那才是關於世界本身的大更新。

他承認過去二十年 AI 的發展改變了他的第一類認知,很多他以為必須理解原理才能做到的事,不理解也做到了。第二類認知沒變。他沒有因為看見 Bing 說話,就覺得自己對智慧的定義是個愚蠢的定義。

他對 GPT-4 的總體判斷也沒變:它還沒有人那麼聰明。變的只是他對“繼續堆層能走多遠”的估計。

一個人怎麼在不確定裡持續更新自己

整期對話最值得看的,是一個人怎麼在高度不確定的地帶持續更新自己。

尤德科夫斯基有一套很硬的操作習慣。他會明確區分“我的結論”和“我的信心”,會指出自己正在呼叫哪一段可能已經失效的舊直覺,會在承認錯誤之後追問:下一次我會往哪個方向錯。他也會在說出一堆具體數字和年份之後,加一句免責宣告:全憑記憶,很可能有錯。

他寫過一篇《AGI Ruin: A List of Lethalities》,把 AI 導致人類毀滅的種種路徑逐條列出來。這份清單之所以有影響力,是因為它把“末日”這個籠統的詞拆成了可以逐條反駁的技術論點。一個人願意把自己的信念攤開到這種顆粒度,別人才有機會指出他哪一條錯了。

而他對外的態度始終一致:別美化我,也別美化我的對手,把話聽準。這個行業正在決定要不要開源下一代模型,這條標準比任何一條安全原則都更管用。

至於他自己最擔心的事,說得很樸素。人類現在做的,是在完全不理解手裡東西的情況下,把它的規模繼續往上推。他不確定 GPT-4 會不會出事,他給的機率相當低。他不確定下一代會不會,那個“不確定”裡帶著他很少流露的猶豫。

一個花了二十年預測災難的人,在災難的可能起點上,說自己可能又錯了。這種誠實,比任何判決都更值得認真對待。

如果真的想從這期對話裡帶走些什麼,可以試試這些:

  • 給自己設一個校準習慣。每次說出“我有 90% 把握”,記下來,一個月後回看實際命中率。校準能力不靠感覺,靠記錄。
  • 定期問自己:我最近一次被現實打臉是往哪個方向錯的?如果連續幾次都朝同一側錯,說明推理裡有系統性偏差,需要修的是那一層,而不是結論。
  • 承認錯誤之後,檢查自己有沒有掉進“反向愚蠢”。上一條判斷錯了,不構成新判斷正確的證據。
  • 區分“我理解你的立場”和“我仁慈地解讀你的立場”。前者經得起對方本人核對,後者只是你覺得好聽。
  • 當有人告訴你某個 AI“有意識”或“只是在模仿”時,先問這個判斷的依據是什麼。目前的答案多半是:沒有人知道。保持“不知道”的狀態,比急著站隊更接近事實。
  • 關注實際決策點,而不是輿論熱度。真正影響走向的是誰在訓練多大規模的模型、訓練完放不放出、開不開源、算力賣給了誰。這些事發生在論文和推特之外。

We're talking a lot about transformer networks, language models that encode the wisdom of the internet. Now, when you encode the wisdom in the internet and you collect and encode the rich, rich, rich complex signal from your very body, when those two things are combined, the transformative effects of the optimized trajectory you could take through life. At least advice for what trajectory is likely to be optimal is going to change a lot of things. It's going to inspire people to be better. It's going to empower people to do all kinds of crazy stuff that pushes their body to the limit because their body is healthy. Anyway, I am super excited for personalized data driven decisions, not some kind of generic population database decisions. Get special savings for a limited time when you go to insidetracker dot com slash lex. This is a lexfriedman podcast to support it. Please check out our sponsors in the description. And now, dear friends, here is Eliezer Yudkowsky. What do you think about GPT four? How intelligent is it? It is a bit smarter than I thought this technology was going to scale to, and I am a bit worried about what the next one will be like. Like this particular one, I think I hope there is nobody inside there, because you know, be sucked to be stuck inside there. Um, but we don't even know the architecture at this point, because OpenAI is very properly not telling us. And yeah, like giant inscrutable matrices of floating point numbers. I don't know what's going on in there. Nobody's knows what's going on in there. All we have to go by are the external metrics. On the external metrics, if you ask it to write a self aware fortune green text, it will start writing a green text about how it has realized that it's an AI writing a green text and like oh well so. That's probably not quite what's going on in there in reality, but we're we're kind of like blowing past all the science fiction guardrails. Like we are past the point where in science fiction people would be like, "Whoa, wait, stop that thing's alive. What are you doing to it?" And it's probably not. Nobody actually knows. We don't have any other guardrails. We don't have any other tests. We don't have any lines to draw on the sand and say like, "Well, when we get this far, we will start to worry about what's inside there." So if it were up to me, I would be like, "Okay, like this far, no further. Time for the summer of AI where we have planted our seeds and now we like wait and reap the rewards of the technology we've already developed and don't do any larger training runs than that." Which to be clear, I realize requires more than one company agreeing to not do that. And take a rigorous approach for the whole AI community to investigate whether there is somebody inside there. That would take decades. Like having any idea of what's going on in there, people have been trying for a while. It's a poetic statement about if there is somebody in there, but I feel like it's also a technical statement, or I hope it is one day. Which is a technical statement with the Alan Turing tried to come up with with the Turing test. Do you think it's possible to definitively or approximately figure out if there is somebody in there, if there is something like a mind inside this large language model? I mean, there is a whole bunch of different sub questions here. There is a question of like, is there consciousness? Is there qualia? Is this a object of moral concern? Is this a moral patient? Like, should we be worried about how we're treating it? And then there is questions like, how smart is it exactly? Can it do X? Can it do Y? And we can check how it can do X and how it can do Y. Unfortunately, we've gone and exposed this model to a vast corpus of text of people discussing consciousness on the internet, which means that when it talks about being self aware, we don't know to what extent it is repeating back what it has previously been trained on for discussing self awareness. Or if there is anything going on in there, such that it would start to say similar things spontaneously. Among the things that one could do if one were at all serious about trying to figure this out is train GPT three to detect conversations about consciousness, exclude them all from the training data sets, and then retrain something around the rough size of GPT four and no larger. With all of the discussion of consciousness and self awareness and so on missing, although you know. Hard hard bar to pass, you know like humans are self aware and we're like self aware all the time. We like talk about what we do all the time, like what we're thinking at the moment all the time. But nonetheless, like get rid of the explicit discussion of consciousness. I think therefore I am and all that. And then try to interrogate that model and see what it says, and it still would not be definitive. But nonetheless, I don't know. I feel like when you run over the science fiction guardrails, like maybe this thing, but what about GPT? Maybe maybe not this thing, but like what about GPT five? You know this this would be a good place to to pause. On the topic of consciousness, you know there is so many components to even just removing consciousness from the data set. Emotion, the display of consciousness, the display of emotion, feels like deeply integrated with the experience of consciousness. So the hard problem seems to be very well integrated with the actual surface level illusion of consciousness. So displaying emotion, I mean, do you think there is a case to be made that we humans when we're babies are just like GPT that we're training on human data on how to display emotion versus feel emotion, how to show others, communicate others. That I am suffering, that I am excited, that I am worried, that I am lonely and I miss you and I am excited to see you. All of that is communicated. That's a communication skill versus the actual feeling that I experience. So we need that training data as humans too, that we may not be born with that how to communicate the internal state, and that's in some sense. If we remove that from GPT four's data set, it might still be conscious but not be able to communicate it. So I think you are going to have some trouble difficulty removing all mention of emotions from GPT's data set. I would be relatively surprised to find that it has developed exact analogs of human emotions in there. I think that humans have. Well, like have like emotions even if you don't tell them about those emotions when they're kids. It's not quite exactly what various blanks blank slatists tried to do with the new Soviet man and all that, but you know if you try to raise people perfectly altruistic. They still come out selfish. You try to raise people sexless, they still develop sexual attraction. You know we we have some notion in humans not in AI's of like where the brain structures are that implement this stuff and it is really remarkable thing I say in passing that. Despite having complete read access to every floating point number in the GPT series, we still know vastly more about the the architecture of human thinking than we know about what goes on inside GPT despite having like vastly better ability to read GPT. Do you think it's possible? Do you think that's just a matter of time? Do you think it's possible to investigate and study the way neuroscientists study the brain, which is look into the darkness, the mystery of the human brain by just desperately trying to figure out something and to form models and then over a long period of time actually start to figure out what regions of the brain do certain things, what different kinds of neurons when they fire, what that means, how plastic the brain is, all that kind of stuff. You slowly start to figure out different properties of the system. Do you think we can do the same thing with language models? Sure, I think that if you know like half of today's physicists stop wasting their lives on string theory or whatever, and go off and study what goes on inside transformer networks. Then in you know like thirty forty years, we'd probably have a pretty good idea. Do you think these large language models can reason? They can play chess. How are they doing that without reasoning? So you are somebody that spearheaded the movement of rationality. So reason is important to you. Is so is that is a powerful important word, or is it like how difficult is the threshold of being able to reason to you and how impressive is it? I mean. In my writings on rationality, I have not gone making a big deal out of something called reason. I have made more of a big deal out of something called probability theory, and that's like well, your reasoning, but you are not doing it quite right. And you should reason this way instead. And interestingly, like people have started to get preliminary results showing that reinforcement learning by human feedback has made. The GPT series worse in some ways, in particular like it used to be well calibrated. If you trained it to put probabilities on things, it would say eighty percent probability and be right eight times out of ten. And if you apply reinforcement learning from human feedback, the the like nice graph of like. Like seventy percent seven out of ten sort of like flattens out into the graph that humans use where there is like some very improbable stuff and. Likely probable maybe, which all means like around forty percent and then certain. Yeah, so like it's like it used to be able to use probabilities, but if you apply, but if you like try to teach it to talk in a way that satisfies humans, it it it gets worse at probability in the same way that humans are. And that's a that's a bug not a feature. I would call it a bug, although such a fascinating bug. But but but yeah, so so like reasoning, like it's doing pretty well on various tests that people used to say would require reasoning, but you know rationality is about. When you say eighty percent, does it happen eight times out of ten? So what are the limits to you of these transformer networks of of neural networks? What's if if reasoning is not impressive to you, or it is impressive but there is other levels to achieve. I mean, it's just not how I carve up reality. What's if reality is a cake? What are the different layers of the cake or the slices? How do you carve it? You can use a different food if you like. It's I don't think it's as smart as a human yet. I do like back in the day I went around saying like I do not think that just stacking more layers of transformers is going to get you all the way to AGI. And I think that GPT four is past where I thought this paradigm was going to take us. And I you know you want to notice when that happens you want to say like whoops well I guess I was incorrect about what happens if you keep on stacking more transformer layers. And that means I don't necessarily know what GPT five is going to be able to do. That's a powerful statement. So you are saying like your intuition initially is now appears to be wrong. Yeah, it's good to see that you can admit in some of your predictions to be wrong. You think that's important to do, because you make several very throughout your life you've made many strong predictions and statements about reality and you evolve with that. So maybe that will come up today about our discussion. So you are okay being wrong. I'd rather not be wrong next time. It's a bit ambitious to go through your entire life never having been wrong. Um, one can aspire to be well calibrated, like not so much think in terms of like was I right was I wrong, but like when I said ninety percent that it happened nine times out of ten. Yeah, like whoops is the sound we make is is the sound we emit when we improve. Beautifully said, and somewhere in there we can connect the name of your blog less wrong. I suppose that's the objective function. The name less wrong was I believe suggested by Nick Bostrom and it's after someone's epigraph actually forget who's who said like we never become right we just become less wrong. Um, what's the something something to easy to confess just error and error and error again but less and less and less. Yeah, that's that's a good thing to strive for. So what has surprised you about GPT four? That you found beautiful as a scholar of intelligence, of human intelligence, of artificial intelligence, of the human mind. I mean, beauty does interact with the screaming horror. Is the beauty in the horror? But but like beautiful moments, well, somebody asked Bing Sydney to describe herself and fed the resulting description into one of the stable diffusion things. I think. And you know she, you know it's she's pretty and this is something that should have been like an amazing moment. Like the AI describes herself, you get to see what the AI thinks the AI looks like. Although you know the the thing that's doing the drawing is not the same thing that's outputting the text. Um, and it's it does happen the way that it would happen in that it happened in the old school science fiction when you ask an AI to make a picture of what it looks like. Um, not just because we're two different AI systems being stacked that don't actually interact, it's not the same person. But also because the AI was trained by imitation in a way that makes it very difficult to guess how much of that it really understood and probably not actually all a bunch. Um although although GPT four is like multimodal and can like draw vector drawings of things that make sense and like does appear to have some kind of. Spatial visualization going on in there, but like the the pretty picture of the like girl with the with the steam punk goggles on her head. If I am remembering correctly, what she looked like, like it didn't see that in full detail. It just like made a description of it and stable diffusion output it. And there is the concern about how much the discourse is going to go completely insane once the AI is all look like that and like are actually look like people talking. Um, and yeah, there is like another moment where somebody is asking Bing about um. Like, well, I like fed my kid green potatoes, and they have the following symptoms, and Bing is like that. Selenine poisoning, and like call an ambulance, and the person's like, I can't afford an ambulance. I guess if like this is. Time for like my kid to go. That's God's will, and the main Bing thread says, gives the like message of like I cannot talk about this anymore. And the suggested replies to it say, please don't give up on your child. Selenine poisoning can be treated if caught early. And you know if that happened in fiction, that would be like the AI cares. The AI is bypassing the block on it to try to help this person. And is it real? Probably not, but nobody knows what's going on in there. It's part of a process where these things are not happening in a way where we. Somebody figure it out how to make an AI care, and we know that it cares, and we can acknowledge it's caring now. It's being trained by this imitation process followed by reinforcement learning on human feedback, and we're like trying to point it in this direction, and it's like pointed partially in this direction, and nobody has any idea what's going on inside it. And if there was a tiny fragment of real caring in there, we would not know. It it's not even clear what it means exactly, and things are clear cut in science fiction. We'll talk about the the horror and the terror and the where the trajectories this can take. But this seems like a very special moment. Just a moment where we get to interact with a system that might have care and kindness and emotion and maybe something like consciousness. And we don't know if it does, and we're trying to figure that out, and we're wondering about what is what it means to care. We're trying we're trying to figure out almost different aspects of what it means to be human about the human condition by looking at this AI that has some of the properties of that. It's almost like this this subtle fragile moment in the history of the human species. We're trying to almost put a mirror to ourselves here. Except that's probably not yet. It probably isn't happening right now. We are we are boiling the frog. We are seeing increasing signs bit by bit. Because like not but not like spontaneous signs because people are trying to train the systems to do that using imitative learning and the imitative learning is like spilling over and having side effects and. And the most photogenic examples are being posted to Twitter, rather than being examined any systematic way. So when you when you when you have when you are boiling a frog like that, you are going to get like like first is going to come the the Blake Lemines. Like first, you are going to like have you are going to have like a thousand people looking at this. And one out and the one person out of a thousand who is most credulous about the signs is going to be like that thing is sentient. Well, nine hundred and ninety-nine out of a thousand people think almost surely correctly though we don't actually know that he's mistaken. And so the like first people to say like sentient look like idiots, and humanity learns lesson that when something claims to be sentient and claims to care, it's fake because it is fake because we have been training them using imitative learning rather than and this is not spontaneous. Um and they keep getting smarter. Do you think we would oscillate between that kind of cynicism? That AI systems can't possibly be sentient. They can't possibly feel emotion. They can't possibly like this kind of um yeah cynicism about AI systems and then oscillate to a state where. We empathize with the AI systems. We give them a chance. We see that they might need to have rights and respect and. Similar role in society as humans. You are going to have a whole group of people who can just like never be persuaded of that because to them like. Being wise, being cynical, being skeptical is to be like oh well machines can never do that. You are just credulous. It's just imitating. It's just fooling you. And like they would say that right up until the end of the world. And possibly even be right because you know they they are being trained on an imitative paradigm. And you don't necessarily need any of these actual qualities nor to kill everyone. So have you observed yourself. Working through skepticism, cynicism and optimism about the power of neural networks. What what has that trajectory been like for you? It looks like neural networks before two thousand six forming part of an indistinguishable to me. Other people might have had better distinction on it indistinguishable blob of different AI methodologies. All of which are promising to achieve intelligence without us having to know how intelligence works. You had the people who said that if you just like manually program lots and lots of knowledge into the system line by line, at some point all the knowledge will start interacting. It will know enough and it will wake up. Um, you've got people saying that if you just use evolutionary computation, if you try to like mutate lots and lots of organisms that are competing together, that's that's the same way that human intelligence was produced in nature. So we'll do this and it will wake up without having any idea of how AI works. And you've got people saying well we will study neuroscience and we will like learn the we will learn the algorithms off the neurons and we will like imitate them without understanding those algorithms which was a part I was pretty skeptical because it's like hard to reproduce reengineer these things without understanding what they do. Um and like and and so we will get AI without understanding how it works and there were people saying like well we will have giant neural networks that we will train by gradient descent and when they are as large as the human brain they will wake up. We will have intelligence without understanding how intelligence works and from my perspective this is all like an indistinguishable blob of people who are. Trying to not get to grips with the difficult problem of understanding how intelligence actually works. That said, I was never skeptical that evolutionary computation. Would not work in the limit like you throw enough computing power at it, it obviously works. That is where humans come from, and it turned out that you can throw less computing power than that at gradient descent. If you are doing some other things correctly, um and you will get intelligence without having any idea of how it works and what is going on inside. Um, it wasn't ruled out by my model that this could happen. I wasn't expecting it to happen. I wouldn't have been able to call neural networks rather than any of the other paradigms for getting like massive amount like intelligence without understanding it. And I wouldn't have said that this was a particularly smart thing for a species to do, which is an opinion that has changed less than my opinion about whether you or not you can actually do it. Do you think AGI could be achieved with a neural network as we understand them today? Yes, just flatly last yes the question is whether the current architecture of stacking more transformer layers which for all we know GPT four is no longer doing because they're not telling us the architecture which is a correct decision. Oh correct decision. I had a conversation with Sam Altman. We'll return to this topic a few times. He turned the question to me of how open should OpenAI be about GPT four. Would you open source the code? He asked me. Because I provided as criticism saying that while I do appreciate transparency, OpenAI could be more open. And he says we struggle with this question. What would you do? Change their name to closed AI, and like sell GPT four to business backend applications that don't expose it. To consumers and venture capitalists and create a ton of hype and like pour a bunch of new funding into the area. But don't too late now. But don't you think others would do it? Eventually, you shouldn't do it first. Like if if if you already have giant nuclear stockpiles, don't build more. If some other country starts building a larger nuclear stockpile, then sure build. Then you know, even then maybe just have enough nukes. You know there are these things are not quite like nuclear weapons. They spit out gold until they get large enough and then ignite the atmosphere and kill everybody. Um, and there is something to be said for not destroying the world with your own hands even if you can't stop somebody else from doing it. But but open sourcing it no that that's just sheer catastrophe. The whole notion of open sourcing this was always the wrong approach the wrong ideal. There are there are places in the world where open source is a noble ideal and. Building stuff you don't understand that is difficult to control that where if you could align it it would take time. You'd have to spend a bunch of time doing it. That is that is not a place for open source because. Then you just have like powerful things that just like go straight out the gate without anybody having had the time to have them knock kill everyone. So can we still man the case for some level of transparency and openness? Maybe open sourcing. So the case could be that because GPT four is not closed to AGI if that's the case. That this does allow open sourcing or being open about the architecture or being transparent about maybe research and investigation of how the thing works of all the different aspects of it. Of its behavior, of its structure, of of its training processes of the data was trained on everything like that. That allows us to gain a lot of insights about alignment about the alignment problem to do really good AI safety research while the system is not too powerful. Can you make that case that it it could be open source? I do not believe in the practice of steel Manning. There is something to be said for trying to pass the ideological Turing test where you describe. Your opponent's position, the disagreeing person's position, well enough that somebody cannot tell the difference between your description and their description. But steel Manning, no, like okay, well this is where you and I disagree here. That's interesting. Why don't you believe in steel Manning? I do not want okay. So for one thing, if somebody's trying to understand me, I do not want them steel Manning my position. I want them to describe to to like try to describe my position the way I would describe it not what they think is an improvement. Well, I think that is what steel Manning is is the most charitable interpretation. I don't want to be interpreted charitably. I want them to understand what I am actually saying. If they go off into the land of charitable interpretations, they're like often their land of like. The the stuff they're imagining and not trying to understand my own viewpoint anymore. Well, I'll put it differently then just to push on this point. I would say it is restating what I think you understand under the empathetic assumption that Eleazer is brilliant. And have honestly and rigorously thought about the point he is made. Right, so if there is two possible interpretations of what I am saying and one interpretation is really stupid and whack and doesn't sound like me and doesn't fit with the rest of what I've been saying. And one interpretation, you know, sounds like some like something a reasonable person who believes the rest of what I believe would also say. Go with the second interpretation. That's steel Manning. That's that's a good guess. If on the other hand you like there is like something that sounds completely whack and something that sounds like a little less completely whack but you don't see why I would believe in it doesn't fit with the other stuff I say. But you know that sounds like less whack and you can like sort of see you could like maybe argue it. Then you probably have not understood it. See okay, I am going to this is fun because I am going to linger on this. You know you wrote a brilliant blog post AGI ruin a list of lethalities right and it was a bunch of different points and I would say that some of the points are bigger and more powerful than others. If you were to sort them, you probably could you personally and to me steel Manning means like going through the different arguments and finding the ones that are really the most. Like powerful, if people like TLDR like what should you be most concerned about and bringing that up in a strong, compelling, eloquent way. These are the points that Eleazer would make to to make the case in this case that AI is going to kill all of us. With that that that's what steel Manning is is presenting it. In a really nice way, the summary of my best understanding of your perspective. That because to me there is a sea of possible presentations of your perspective and steel Manning is doing your best to do the best one in that sea of different perspectives. Do you believe it? Do you believe in what? Like these things that you would be presenting as like the strongest version of my perspective. Do you believe what you would be presenting? Do you think it's true? I I am a big proponent of empathy. When I see the perspective of a person, there is a part of me that believes it if I understand it. I mean, I've especially in political discourse in geopolitics, I've been hearing a lot of different perspectives on the world. And I hold my own opinions, but I also speak to a lot of people that have a very different life experience and a very different set of beliefs. And I think there has to be epistemic humility. In stating what is true, so when I empathize with another person's perspective, there is a sense in which I believe it is true. I think probabilistically I would say in the way you think about. Do you bet money on it? Do you bet money on their beliefs when you believe them? I will allow to do probability. Sure, you can state a probability that yes, there is a loose, there is a probability, there is a there is a probability, and I think empathy is allocating a non zero probability to belief. In some sense, for time. If you've got someone on your show who believes in the Abrahamic deity classical style, somebody on the show who's a young Earth creationist, do you say I put a probability on it then that's my empathy. When you reduce beliefs into probabilities, it starts to get you know we can even just go to flat Earth. Is the Earth flat? The thing it's a little more difficult nowadays to find people who believe that unironically. But fortunately, I think well it's hard to know unironic, yeah. From ironic, but I think there is quite a lot of people that believe that yeah it's. There is a space of argument where you are operating, rationally in the space of ideas, but then there is also. A kind of discourse where you are operating in the space of subjective experiences and life experiences. Like I think what it means to be human is more than just. Searching for truth, it's just operating of what is true and what is not true. I think there has to be deep humility that we humans are very limited in our ability to understand what is true. So what probability do you assign to the young Earth creationist beliefs then? I think I have to give non zero out of your humility. Yeah, but like three. I think I would it would be irresponsible for me to give a number because the listener, the way the human mind works. We're not good at hearing the probabilities, right? You hear three. What is what is three exactly? Right, they're going to hear, they're going to like. Well, there is only three probabilities. I feel like zero fifty percent and one hundred percent in the human mind or something like this, right? Well, zero forty percent and one hundred percent is a bit closer to it. Based on what happens to Chat GPT after RLHF to speak humanese. Brilliant, yeah, that's really interesting. I didn't I didn't know those negative side effects of RLHF. That's fascinating, but just to return to the. Open AI closed AI. Also, like quick disclaimer, I am doing all this for memory. I am not pulling out my phone to look it up. It is entirely possible that the things I am saying are wrong. So thank you for that disclaimer. So and thank you for being willing to be wrong. That's beautiful to hear. I think being willing to be wrong is a sign of a person who's done a lot of thinking about this world and. Has been humbled by the mystery and the complexity of this world, and I think a lot of us are resistant to admitting we're wrong because it hurts. It hurts personally, it hurts especially when you are public human. It hurts publicly because people people point out every time you are wrong. Like look, you changed your mind. You are hypocrite. You are an idiot. Whatever whatever they want to say. Oh, I block those people and then I never hear from them again on Twitter. Well, the point is the point is to not let that pressure public pressure affect your mind and be willing to be in the privacy of your mind. To contemplate the possibility that you are wrong and the possibility that you are wrong about the most fundamental things you believe like people who believe in a particular god, people who believe that their nation is the greatest nation on earth, but all those kinds of beliefs that are core to who you are when you came up. To raise that point to yourself in the privacy of your mind to say maybe I am wrong about this. That's a really powerful thing to do, and especially when you are somebody who's thinking about topics that can. About systems that can destroy human civilization or maybe help it flourish. So thank you, thank you for being willing to be wrong. About open AI. So you really, I just would love to linger on this. You really think it's wrong to open source it. I think that burns the time remaining, until everybody dies. I think we are not on track, to learn remotely near fast enough. Even if it were open sourced. Um, yeah, that's, I, it's easier to think that you might be wrong about something when being wrong about something is the. Is is the only way that there is hope, and it doesn't seem very likely to me that. The particular thing I am wrong about is that this is a great time to open source GPT four. If humanity was trying to survive at this point in the straightforward way, it would be like shutting down the big GPU clusters. No more giant runs. It's questionable whether we should even be throwing GPT four around, although that is a matter of conservatism rather than a matter of my predicting that catastrophe will follow from GPT four. That is something which I put like a pretty low probability. But also like when I when I say like I put a low probability on it, I can feel myself reaching into the part of myself that thought that GPT four was not possible in the first place. So I do not trust that part as much as I used to. Like the trick is not just to say I am wrong, but like okay well I was I was wrong about that. Like, can I get out ahead of that curve and like predict the next thing I am going to be wrong about? So the set of assumptions or the actual reasoning system that you were leveraging in making that initial statement prediction. How can you adjust that to make better predictions about GPT four five six? You don't want to keep on being wrong in a predictable direction. Yeah, like being wrong anybody has to do that walking through the world. There is like no way you don't say ninety percent and sometimes be wrong. In fact, you'd happen at least one time out of ten if you are well calibrated when you say ninety percent. The the undignified thing is not being wrong. It's being predictably wrong. It's being wrong in the same direction over and over again. So having been wrong about how far neural networks would go and having been wrong specifically about whether GPT four would be as impressive as it is. When I like, when I say like well I don't actually think GPT four causes a catastrophe I do feel myself relying on that part of me that was previously wrong and that does not mean that the answer is now in the opposite direction. Reverse stupidity is not intelligence. But it does mean that I that I say it with a with a worried note in my voice. It's like still my guess, but like you know it's a place where I was wrong. Maybe you should be asking Gurn Gurn Brannen. Gurn Brannen has been like writer about this than I have. Maybe ask him if you think if if he thinks it's dangerous. Rather than asking me, I think there is a lot of mystery about what intelligence is, what AGI looks like. So I think all of us are rapidly adjusting our model. That the point is to be rapidly adjusting the model versus having a model that was right in the first place. I do not feel that seeing Bing has changed my model of what intelligence is. It has changed my understanding of what kind of work can be performed by which kind of processes and by which means. Does not change my understanding of the work. There is a difference between thinking that the right flyer can fly and then like it does fly and you are like oh well I guess you can do that with wings with with fixed wing aircraft and being like oh it's flying this changes my picture of what the very substance of flight is that's like a stranger update to make and Bing has not yet updated me in that way. Um yeah that the laws of physics. Are actually wrong that kind of update. No no like just like oh like I define intelligence this way but I now see that was a stupid definition. I don't feel like the way that things have played out over the last twenty years has caused me to feel that way. Can we try to, um on the way to talking about AGI ruin a list of lethalities that blog and and other ideas around it. Can we try
