“Another dramatic sign of changing times: Sam Altman, who ridiculed my 2022 critique of LLMs that argued that scaling would not bring us to AGI and that we would need architectures has just argued that”
Our reading: Sam Altman, who ridiculed Marcus's 2022 critique arguing that scaling would not bring us to AGI, has just said he bets there is another new architecture to find that would be as big a gain as transformers were over LSTMs, which Marcus calls a dramatic sign of changing times.
No horizon Evidence as of
Limitation: The original post does not identify Marcus or his particular 2022 critique; the attribution rests on secondary commentary [e1, e2].

“Hassabis is no longer on board either, and nor are Sutskever and LeCun. Nadella and Pichai have also hinted at skepticism around scaling.”
Our reading: Hassabis, Sutskever and LeCun no longer believe in scaling as the route to AGI, and Nadella and Pichai have hinted at skepticism about it.
No horizon Evidence as of
Limitation: The record does not establish earlier endorsement and subsequent rejection of scaling alone for everyone described as having changed position.

“Note that in this talk Altman didn’t claim to have found such an architecture. That represents a significant retrenchment from his claim fourteen months ago that “We now know how to build AGI as it’s usually understood.””
Our reading: In this talk Altman did not claim to have found such an architecture, which Marcus says is a significant retrenchment from Altman's claim fourteen months earlier that 'We now know how to build AGI as it's usually understood.'

“AI is supposed to change all that. But so far it hasn’t.”
Our reading: So far, AI has not changed the toll that cancer takes on people.

Causal claim
“Over and over we discover drugs with AI that work on trials in animals but not safely enough in humans; we just don’t understand biology well enough.”
Our reading: Over and over, drugs discovered with AI work in animal trials but are not safe enough in humans, because we just don't understand biology well enough.

“In my 2020 article, The Next Decade in AI, I foresaw all this, and urged the field to start focusing on world (cognitive) models and neurosymbolic AI.”
Our reading: In his 2020 article 'The Next Decade in AI', Marcus foresaw these developments and urged the field to start focusing on world (cognitive) models and neurosymbolic AI.
No horizon Evidence as of
Limitation: Support depends on interpreting 'foresaw all this' as a general warning, rather than a specific prediction of the 2026 Meta and xAI developments.

“the fact that LLMs hallucinate (patently true)”
Our reading: LLMs hallucinate.
No horizon Evidence as of
Limitation: The evidence is a manufacturer's internal evaluation.
Assessment: SupportedSaid
Observation
“It is a misapprehension of LLMs to confuse the things they say with what is true.”
Our reading: What LLMs say should not be taken as true just because they say it; treating their statements as truth misunderstands them.
No horizon Evidence as of
Limitation: The benchmark uses one person's biography and that person's manual judgments; it cannot establish a general error rate.

“Essentially the same argument applies to Claude’s constitution, which amounts to a set of built-in guardrails. OpenAI has those, too!”
Our reading: Claude's constitution is basically a set of built-in guardrails, and OpenAI's models have guardrails too.
No horizon Evidence as of
Limitation: The outcome depends on reading guardrails broadly and amounts to as shorthand.

“Apocalyptic talk is a special case of hype, Sam and Dario both play that card over and over, basically amounting to saying “our tech is so scary it might ruin society, so give us more money so we can make that tech ever faster.””
Our reading: Altman and Amodei both repeatedly use apocalyptic talk, a special case of hype, which basically amounts to saying their tech is so scary it might ruin society so they should be given more money to build it ever faster.
No horizon Evidence as of
Limitation: Hype is an opinion rather than a separately measurable fact.

“How about copyright? OpenAI notoriously trained on practically anything that is “publicly available” whether public domain or not.”
Our reading: OpenAI trained on practically anything publicly available, whether public domain or not.
No horizon Evidence as of

“AI can help in the search for candidate drugs, but we still need to test them. There is zero chance that we double human life span in the next decade.”

“Both, for example, have endlessly hinted that AGI is near, and just quietly moved the deadline back when they didn’t deliver.”
Our reading: Amodei and Altman have repeatedly hinted AGI is near and quietly moved the deadline back when it didn't arrive.

“Millions of people, literally, are angry; many feel betrayed.”
Our reading: Millions of people are angry and many feel betrayed by Altman/OpenAI.
No horizon Evidence as of

Our reading: Generative AI, a system that people shouldn't trust with their taxes, is being used by certain parts of Washington to blow people up.

“Essentially anyone who uses a chatbot is at risk.”
Our reading: Essentially anyone who uses a chatbot is at risk of having their beliefs distorted by sycophantic AI.
No horizon Evidence as of
Limitation: Treating essentially anyone as broad population coverage materially affects the assessment; a weaker claim that ordinary users can be affected is better supported.

Our reading: By proclaiming that LLMs would change the world imminently, doomers contributed to the growth of LLM companies and to the White House thinking LLMs were critical to the nation's survival.

“the point being that doomers, especially those who have screamed that AGI is nigh, have wanted to slow AI acceleration (at least until we could make AI safe) and instead have only accelerated it.”
Our reading: Doomers, especially those who claimed AGI is nigh, wanted to slow AI acceleration (at least until AI could be made safe) but instead have only accelerated it.
