Anthropic’s Coxon quits over RSI race fears
TechCrunch reported on September 9, 2026 that Jacob Coxon, a pretraining researcher who said he spent three years at OpenAI and Anthropic, resigned and wrote on X that labs are “racing straight to self-improving superintelligence and gambling with our lives,” arguing builders “earnestly believe it could kill us all by the end of the decade.” Anthropic alignment lead Evan Hubinger publicly agreed that the team earnestly believes AI could kill all humans, putting his personal estimate above 10% within a decade and saying Anthropic does not yet have a plan to solve alignment for superintelligence; Anthropic did not immediately comment to TechCrunch. This is a resignation and warning attributed to Coxon and Hubinger via TechCrunch, not an Anthropic product launch and not OpenAI’s Alien Mind essay.
