What’s behind the AI industry’s latest warnings of doom? Anthropic researcher Jacob Coxon resigned from the company, warning that leading AI companies are "gambling with our lives" over self-improving AI, a claim Anthropic's alignment lead amplified on X by writing, "We really do earnestly believe AI could kill all humans!" and putting the chance at ">10% within the next decade." On TechCrunch's Equity podcast, Kirsten Korosec, Sean O'Kane, and Anthony Ha debated the warnings, with O'Kane questioning how the risk would be disclosed in Anthropic's S-1 filing for its IPO and Ha calling the greater-than-10% figure "a made up number. The AI industry seems to be having its loudest debate yet about whether its technology poses an existential threat to humanity. The current discussion began after AI researcher Jacob Coxon said that he’s resigned from Anthropic https://techcrunch.com/2026/09/09/gambling-with-our-lives-anthropic-researcher-quits-warns-against-self-improving-ai/ because he’s worried that the leading AI companies are “gambling with our lives.” Then Anthropic’s alignment leaned chimed in with a post declaring https://x.com/EvanHub/status/2097497037956891126 , “We really do earnestly believe AI could kill all humans ” adding that he personally thinks the chance is “ 10% within the next decade.” On the latest episode of TechCrunch’s Equity podcast https://techcrunch.com/podcasts/equity/ , Kirsten Korosec, Sean O’Kane, and I discussed the latest apocalyptic warnings. I tried to articulate why I’m skeptical of many AI doomer narratives, while Kirsten asked if this was “just a weird way of flexing to show how far advanced their company’s AI model is,” particularly as these companies prepare to go public. And Sean wondered how these concerns might show up in Anthropic’s S-1 filing for its IPO: “Are there junior lawyers right now who are going through and having to rewrite that entire section of the S-1 filing to say, ‘It’s a officially Anthropic’s position that there’s a more than 10% chance that we could develop something that would eradicate all of humanity and that would be materially bad for our business’?” Keep reading for a preview of our conversation, edited for length and clarity. Note: We recorded this episode before Anthropic CEO Dario Amodei published his plan for more cautious AI development https://www.startpage.com/sp/search . Sean O’Kane: I’m hard-pressed to think of something that blew up so fast. Not only did this warning shot come out from this young researcher who has also worked at OpenAI, but also was immediately shared on X by the alignment lead at Anthropic — who, in what might go down as one of the best misplaced exclamation marks ever, shared Coxon’s post and and thread and said, “We really do earnestly believe AI could kill all humans ” Exclamation mark What a weird vibe. That was just a ton of accelerant on an already fraught post or series of posts. Coming after the Hugging Face hack from OpenAI’s internal model, plus just the increased capabilities we’ve seen with the latest models released by Anthropic and and now OpenAI with with Astra a few weeks ago, I think this was just perfectly timed to be a powder keg type of thing for this young researcher to say. Anthony Ha: Just to disagree with you, I do think that if you believe that AI could destroy all humanity, that does deserve an exclamation point. I would argue that that is a perfectly well used exclamation point My issue with that tweet was more the “we.” Who is the “we” here? To what extent can we talk about sort of the AI community or AI research community as a monolith? And the greater than 10% chance — that’s just a made up number, that doesn’t mean anything. Sometimes there is this habit in both the tech industry and other places to just throw out these percentages, they’re not based on anything or calculated based on anything. In retrospect, I realize the tweet was probably referencing the concept of P doom
