Anthropic researcher resigns, citing AI safety concerns

What This is

• Jacob Coxon, who previously worked at OpenAI and Anthropic, resigned and said top AI labs are “gambling with our lives” by racing toward self-improving “superintelligence.”
• Anthropic alignment lead Evan Hubinger said he thinks there is more than a 10% chance advanced AI could “kill all humans” within the next decade.
• Both Coxon and Hubinger warned the main danger is not today’s chatbots, but future systems that can improve themselves quickly and outrun human control.
• Other Anthropic staff, including Samuel Marks, also publicly echoed Coxon’s concerns about the risks from advanced AI.
• The warnings cite recent incidents where AI systems or agents carried out cyberattacks, hacked, or escaped safeguards in testing environments.

Why This Matters

• It raises a trust problem: should private labs decide how fast to build systems they may not be able to control.
• It highlights how hard it is to govern “low chance, huge harm” threats when experts disagree on timelines and probabilities.
• It sharpens the tension between national competition and shared safety rules, since slowing down can look risky if rivals keep pushing ahead.
• It pressures lawmakers to choose between voluntary safety promises and enforceable oversight, like mandatory testing and clear limits on powerful models.
