Connor LeahyUS executive director of ControlAI, co-founder of EleutherAI and ConjectureNear certain, 80% to 100%Estimated by usIf such systems would be built — and as I have said, we don’t understand or can’t control them — well, there would be not just one superintelligence, of course, because as it is software, it can be copied. So you would have millions or billions of systems running around, acting in the world in ways that can outcompete us at everything, in ways that we cannot control or understand. It’s very hard to imagine that going well.Democracy Now, AI Superintelligence Is Not a Tool, It’s an Adversary Threatening Humanity: ControlAI’s Connor LeahyAug 20, 2026
Eliezer YudkowskyCo-founder of the Machine Intelligence Research InstituteNear certain, 80% to 100%Estimated by usMany researchers steeped in these issues, including myself, expect that the most likely result of building a superhumanly smart AI, under anything remotely like the current circumstances, is that literally everyone on Earth will die. Not as in “maybe possibly some remote chance,” but as in “that is the obvious thing that would happen.”TIME, Pausing AI Developments Isn't Enough. We Need to Shut it All DownMar 29, 2023
Evan HubingerAlignment Science lead at Anthropic>10%StatedJacob is correct here—we really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade. I believe Anthropic is trying its best, but we do not yet have a plan to solve alignment for superintelligence and are not clearly on track to.Evan Hubinger on XSep 8, 2026

Roman YampolskiyComputer scientist at the University of Louisville, AI safety researcherNear certain, 80% to 100%Estimated by usSo, if we create something smarter than all of us, super intelligence, and as of today no one knows how to control those systems. It's just not a thing anyone knows. Not in theory, not in practice. Then it's up to them what to do with us, and there is quite a number of reasons, rational reasons, game theoretic reasons to not keep us around.djvlad (VladTV), AI Safety Expert Roman Yampolskiy: AI Has a 99.9% Chance of Wiping Out Humanity (Full Interview)Jun 26, 2026
Jan LeikeCo-lead of OpenAI's Superalignment team, at Anthropic since 2024more than 10% and less than 90%StatedYeah.

David DuvenaudComputer science professor at the University of Toronto, former alignment evaluations team lead at Anthropicsomething like 70% to 80%StatedLet me say first of all, by “doom” I mean something like, by 2100, the world is in a state where I can see that almost everything that I value has been destroyed. Maybe we’re not literally dead, but we’ve been forced to be uploaded in some very unfavourable conditions, where it’s just like some crappy lossy copy that never gets run. And I feel like whatever dynamics are in charge of our civilisation are just not going to optimise for anything that seems like it’s going to be valuable. And I guess I would say something like 70% to 80%.80,000 Hours Podcast, David Duvenaud on why 'aligned AI' could still kill democracy (transcript)Aug 21, 2025
Sam HarrisNeuroscientist, philosopher and host of the Making Sense podcastLikely, 35% to 80%Estimated by usI'm going to describe a scenario that I think is both terrifying and likely to occur, and that's not a good combination, as it turns out. And yet rather than be scared, most of you will feel that what I'm talking about is kind of cool. I'm going to describe how the gains we make in artificial intelligence could ultimately destroy us. And in fact, I think it's very difficult to see how they won't destroy us or inspire us to destroy ourselves.TED, Can we build AI without losing control over it? (TEDSummit 2016)Jun 26, 2016

Shane LeggCo-founder of DeepMind, later Chief AGI Scientist at Google DeepMindMaybe 5%, maybe 50%StatedDepends a lot on how you define things. Eventually, I think human extinction will probably occur, and technology will likely play a part in this. But there's a big difference between this being within a year of something like human level AI, and within a million years. As for the former meaning...I don't know. Maybe 5%, maybe 50%.

How do we guarantee it's safe? If you think that's overly dramatic, I'd love to hear your rebuttal. Perhaps I'm missing something.

Richard BlumenthalUS Senator from ConnecticutSerious, 10% to 35%Estimated by usAnd now, artificial general intelligence or AGI, which I know our witnesses are going to address today, provides even more frightening prospects for harm. The idea that AGI might in 10 or 20 years be smarter, or at least as smart as a human being, is no longer that far out in the future. It is very far from science fiction. It is here and now. One to three years has been the latest prediction, in fact, before this Committee. And we know that artificial intelligence that is as smart as human beings is also capable of deceiving us, manipulating us, and concealing facts from us, and having a mind of its own when it comes to warfare, whether it is cyber war or nuclear war or simply war on the ground in the battlefield.Office of Sen.

Stuart RussellProfessor of computer science at UC Berkeley, co-author of Artificial Intelligence: A Modern ApproachSerious, 10% to 35%Estimated by usThen the other branch is that some further breakthroughs happen that do lead to something like AGI in the relatively near term. And then I think the risk would be quite high that we would experience some significant negative outcomes. And you can roughly divide those into irreversible catastrophe or a reversible catastrophe that would be big enough to change both corporate -- the direction of technology that corporations are developing and the views of government about the need to regulate.Musk v.

Emmett ShearCo-founder and former CEO of Twitchsomewhere between 3 to 30%StatedI don't believe in point estimates for probabilities because it's like a bid-esque spread in the market.

These were 1 in 1,000 for Climate and for Nuclear, 1 in 30 for Pandemics and 1 in 10 for Unaligned AI. You are probably all wondering how all of this affects those numbers and what my new numbers are.

How to read it

  • A solid ring is a number the person said. A dashed ring is our estimate from their words, never presented as theirs. We place those in five bands: dismissive (0 to 1%), low (1 to 10%), serious (10 to 35%), likely (35 to 80%) and near certain (80 to 100%). A dashed face can sit anywhere along its band, so its exact spot inside the band means nothing.
  • The numbers do not all measure the same thing. People mean different outcomes, from extinction to a permanent loss of control, over different time spans. Each card says what the person said it was a probability of, and over when, where they said.
  • Every estimate is dated and some are old. Views change. We show the newest and keep the earlier ones on each card.
  • Face size is page views, English Wikipedia page views from Jun 13, 2026 to Sep 10, 2026. It measures how often readers look a person up, not how right they are.
  • The second view adds what each person thinks should happen to AI development, from pause to accelerate, read from their own words.
  • Something wrong or out of date? Tell us, with a link to what the person said. Corrections are logged on the editorial page.
