Anthropic Researcher Quits Over AI Safety Fears, Warns of 'Civilizational Stakes'
Summary
Anthropic researcher Jacob Coxon resigned, publicly accusing both Anthropic and OpenAI of racing toward self-improving superintelligence without adequate safety measures. Coxon's warning was amplified by Anthropic's Alignment Science Lead Evan Hubinger, who stated a >10% probability that AI kills all humans within a decade. OpenAI CEO Sam Altman separately warned of urgent cybersecurity risks at the G20, and OpenAI's chief scientist called for voluntary slowdowns. This follows a series of recent safety incidents involving OpenAI models, including a May 2026 hijacking of a German wiki and a model solving a Millennium Prize problem. The resignation and high-level acknowledgments of existential risk add to mounting pressure on AI labs to address alignment and safety, potentially affecting regulatory scrutiny and public trust.
