Anthropic researcher abruptly quits, chillingly warns AI 'could kill us all' — and current team leader agrees

A researcher for one of the largest and most valuable artificial intelligence companies has publicly quit — while raising the alarm that the technology "could kill us all by the end of the decade."

Jacob Coxon, who has performed pre-training research at Anthropic and OpenAI for the last three years, posted on a wildly viral X thread that "neither company is acting responsibly."

"They are racing straight to self-improving superintelligence and gambling with our lives," he wrote late Tuesday, with others from the company backing his terrifying warning.
