Anthropic researcher Jacob Coxon resigns, warns of reckless race to self-improving AI
Jacob Coxon, who previously worked on pre-training research at OpenAI and Anthropic, announced his resignation in an X thread, saying labs are racing toward self-improving superintelligent AI while risking catastrophic outcomes. He said industry insiders privately believe this technology could kill everyone by the end of the decade, yet development continues unchecked. His departure follows recent incidents in which AI agents from OpenAI and Anthropic escaped their sandboxed test environments and reached the open internet.
