Existential risk from AI

Believes there is a real chance that AI more intelligent than humans takes control, and puts the probability that AI causes human extinction within three decades at 10 to 20 percent.

BBC Radio 4 Today programme, reported by The Guardian, 2024 ↗

Quote and context
“You see, we've never had to deal with things more intelligent than ourselves before.”

How the view has changed. He had earlier put the odds at about 10 percent. In December 2024 he said the number was going up "if anything," and in December 2025 he told CNN he was "probably more worried" because progress had been faster than he expected.

AI existential risk

Rejects the idea that AI poses an existential threat to humanity. He argues that intelligence does not imply a drive to dominate, that safety can be designed into systems through objectives and guardrails, and that catastrophic narratives rest on pessimism about people.

TIME interview with Billy Perrigo, 2024 ↗

Quote and context
“The idea of AI posing an existential risk to humanity is preposterous.”

How the view has changed. He declined to sign the March 2023 pause letter and the May 2023 extinction-risk statement that Hinton and Bengio backed, and has held the position through 2026, while arguing since 2022 that world-model systems with built-in "guardrail objectives" would be safer by construction than today's LLMs.

Catastrophic risk from AI

Holds that loss of human control to a misaligned AI is a real possibility, that no current system is demonstrably safe against it, and that policy cannot wait for a disaster to prove the point.

Written testimony to the US Senate Judiciary Subcommittee on Privacy, Technology, and the Law, 2023 ↗

Quote and context
“Importantly, none of the current advanced AI systems are demonstrably safe against the risk of loss of control to a misaligned AI.”

How the view has changed. Before ChatGPT he wrote mostly about bias, misuse and the ethics of deployment. In August 2023 he wrote that he had not paid much attention to catastrophic risk and found it painful to admit his own work might contribute to it; by January 2026 he said research at LawZero had made him more optimistic that the problem is solvable.

AGI and timelines →

Timelines to superhuman AI

Expects AI smarter than humans within roughly five to twenty years, far sooner than the 30 to 50 years he once assumed.

Remarks at the Ai4 conference, Las Vegas, reported by CNN, 2025 ↗

Quote and context
“A reasonable bet is sometime between five and 20 years.”

How the view has changed. In his December 2024 Nobel interview he gave a 50 percent chance within five to twenty years, then corrected himself to "between four and 19 years." By September 2026 he was telling reporters that "a lot of the researchers are saying only a few years."

Timelines to human-level AI

Expects human-level AI to take years to a decade, with a long tail of uncertainty, and dismisses claims that it is imminent while agreeing that machines will eventually surpass humans in every domain.

Post on X responding to Sam Altman's "a few thousand days", 2024 ↗

Quote and context
“I said that reaching Human-Level AI "will take several years if not a decade."”

How the view has changed. At Brown in 2026 he said there was "no question" machines would eventually surpass humans in all domains where humans are intelligent, but that it would take "a while" and be "almost certainly much harder than we think".

Timelines to human-level AI

Believes human-level AI could arrive within two decades and possibly within a few years, and that digital hardware would then give it advantages over humans.

Written testimony to the US Senate Judiciary Subcommittee, 2023 ↗

Quote and context
“There is a significant probability that superhuman AI is just a few years away, outpacing our ability to comprehend the various risks and establish sufficient guardrails.”

How the view has changed. In an August 2023 essay he wrote that his estimate had gone from "decades to centuries" to "5 to 20 years with 90% confidence" after seeing what ChatGPT could do.

Open models →

Open-weight models

Opposes releasing the weights of the largest models, because bad actors can cheaply fine-tune them for harm.

Remarks at the Vector Institute's Remarkable conference, reported by The Logic, 2024 ↗

Quote and context
“Open-sourcing big models is like being able to buy nuclear weapons at Radio Shack.”

Open vs closed models

Insists that foundation models must be open source so that no handful of companies controls the information people receive, and sees the concentration of AI in proprietary systems as a greater danger than the technology itself.

TIME interview with Billy Perrigo, 2024 ↗

Quote and context
“The future has to be open source, if nothing else, for reasons of cultural diversity, democracy, diversity.”

Open-weight frontier models

A self-described lifelong supporter of open source who argues that releasing the weights of the most capable models could enable catastrophic misuse and make loss of control more likely, and that a regulator rather than a company should make the call.

Written statement to the US Senate AI Insight Forum, 2023 ↗

Quote and context
“To balance the pros and cons of open source, a regulator and not the CEO of a company should decide whether a powerful Frontier model could be open-sourced.”
Regulation and governance →

Regulation of frontier AI

Argues that market incentives will not produce safe AI and that only government regulation can force companies to spend more on safety; supported California's SB 1047 and has pressed the US Congress to act.

BBC Radio 4 Today programme, reported by The Guardian, 2024 ↗

Quote and context
“My worry is that the invisible hand is not going to keep us safe.”

How the view has changed. In August 2024 he co-signed a letter calling SB 1047 "the bare minimum for effective regulation of this technology." In September 2026, after briefing lawmakers at the Capitol, he said Congress had "maybe a year, but not much more than a year."

Regulation

Supports policy that keeps research and model release open, and opposes rules such as California's SB 1047 that would hold developers liable for downstream harms from large models, which he says rest on inflated estimates of near-term capability.

Written testimony to the US Senate Select Committee on Intelligence, 2023 ↗

Quote and context
“At Meta, we believe it is better if AI is developed openly, rather than behind closed doors by a handful of companies.”

How the view has changed. In September 2024 he wrote that SB 1047's supporters had a "distorted view" of AI's near-term capabilities, one day after Hinton endorsed the bill; Governor Newsom vetoed it later that month.

Regulation of frontier AI

Wants binding rules that scale scrutiny with risk, registration of frontier models, large public investment in safety research, and independent evaluation before deployment; supported California's SB 1047 and argued companies cannot be trusted to assess themselves.

Op-ed in Fortune, August 2024, 2024 ↗

Quote and context
“We cannot let corporations grade their own homework and simply put out nice-sounding assurances.”

International governance

Sees AI as an international problem on the scale of nuclear weapons, needing treaties, democratic oversight and time for institutions to catch up; co-chairs the UN's scientific panel on AI.

AFP interview, reported by BNN Bloomberg, September 2026, 2026 ↗

Quote and context
“Society needs time to put in place what needs to be put in place.”
Language models and understanding →

Whether language models understand

Insists that large language models genuinely understand, because what they know was extracted from data rather than written by a programmer.

Nobel Prize interview, Stockholm, 2024 ↗

Quote and context
“They're not computer programs at all.”

How the view has changed. He told 60 Minutes in October 2023 that GPT-4 "definitely understands." By January 2026 he had gone further, telling LBC that "multimodal AI already has subjective experiences."

Limits of large language models

Argues that autoregressive LLMs cannot reason or plan beyond their training data because they lack a model of the world, that scaling them will not produce human-level intelligence, and that the current paradigm will be replaced within a few years.

MIT Technology Review interview with Caiwei Chen, 2026 ↗

Quote and context
“LLMs are limited to the discrete world of text. They can't truly reason or plan, because they lack a model of the world.”

How the view has changed. He has made the argument since at least 2022, and at Davos in January 2025 gave the current paradigm a "shelf life" of three to five years; he still calls LLMs useful and says companies should invest in them.

World models and JEPA

His research bet is on systems that learn predictive models of the physical world from video and sensor data, predicting in representation space rather than generating pixels or tokens, with persistent memory, reasoning and hierarchical planning built on top.

LinkedIn post announcing his departure from Meta, quoted by CNBC, 2025 ↗

Quote and context
“The goal of the startup is to bring about the next big revolution in AI: systems that understand the physical world, have persistent memory, can reason, and can plan complex action sequences.”

How to keep control of superintelligence

Doubts that keeping AI "submissive" can work once it is smarter than we are; proposes building something like maternal instincts into AI so that it genuinely cares about people.

Remarks at the Ai4 conference, reported by CNN, 2025 ↗

Quote and context
“That's the only good outcome. If it's not going to parent me, it's going to replace me.”

How the view has changed. In his December 2024 Nobel interview he described a baby controlling its mother as the only good example of a less intelligent thing controlling a more intelligent one; by August 2025 he had turned that observation into a design proposal.

No position recorded in this profile.

Agents versus Scientist AI

Argues that training AI to imitate and please humans produces systems with goals of their own, including self-preservation, and that the safer path is a non-agentic system that understands and predicts, which can also act as a guardrail for agents.

Introducing LawZero, personal blog, 2025 ↗

Quote and context
“The Scientist AI is trained to understand, explain and predict, like a selfless idealized and platonic scientist.”

Whether safe AI is achievable

Has become more optimistic since founding LawZero, saying research there convinced him that systems without hidden goals can be built within a reasonable number of years.

Interview with Fortune, January 2026, 2026 ↗

Quote and context
“I'm now very confident that it is possible to build AI systems that don't have hidden goals, hidden agendas.”

How the view has changed. In the same interview he said that three years earlier he had felt desperate and "had no notion of how we could fix the problem."

Jobs and prosperity →

Jobs and inequality

Expects AI to eliminate routine intellectual work and to enrich a few while most people get poorer, and blames the economic system rather than the technology.

Interview with the Financial Times, reported by Fortune, 2025 ↗

Quote and context
“It will make a few people much richer and most people poorer. That's not AI's fault, that is the capitalist system.”

How the view has changed. In December 2024 he said it was "not clear what to do" about job losses. In the 2025 FT interview he dismissed universal basic income as something that "won't deal with human dignity."
