Imagine working for one of the world’s biggest AI companies , and then quitting because you’re scared of where AI is going.
That’s exactly what Jacob Coxon, an AI researcher who worked at both OpenAI and Anthropic, says he has done.
In a viral post on X, Coxon announced his resignation from Anthropic and accused leading AI labs of racing toward self-improving superintelligence without having figured out how to control it.
His warning was blunt: the people building these systems, he says, genuinely believe that AI could potentially “kill us all by the end of the decade.”
And then things got even more unsettling.
Anthropic researcher Evan Hubinger publicly agreed with Coxon’s concerns. Hubinger said his team genuinely believes AI could potentially kill all humans and estimated the probability at more than 10% within the next decade.
Coxon’s post reportedly reached more than 100 million people, turning a technical AI-safety debate into a mainstream conversation.
Anthropic and other AI companies argue that they are actively working on safety and alignment. But the bigger question remains:
If the people building AI are worried about what they’re creating… should we be?
