AI leaders weigh existential risk as Anthropic researcher resigns with dire warning

Anthropic researcher Jacob Coxon resigned, publicly warning that AI researchers 'genuinely believe it could kill all of us by the end of the decade,' intensifying public debate among tech leaders like Musk, Zuckerberg, and Altman. The claim is an individual's assertion, not corroborated by data, and reflects ongoing internal industry disagreement over AI existential risk. This matters as it could influence regulatory momentum and public perception of AI safety.
