Alex Turner backs Coxon's warning that advanced AI could kill everyone
Alex TurnerFormer Google DeepMind AI researcher, self-identified in the post and described as such in Newsweek's reporting.
Turner supports Coxon's account that many researchers believe advanced AI could kill everyone and says preventing that outcome was his job at Google DeepMind. His post does not directly judge Anthropic's conduct or advocate a particular remedy.
“Jacob is right: many researchers believe they are building something that could kill everyone on the planet.”

Where this statement fits
Is Anthropic acting responsibly while advancing toward recursive self-improvement?
Jacob Coxon resigned from Anthropic and said that Anthropic and OpenAI are acting irresponsibly by racing toward self-improving superintelligence. In a fuller interview, he praised Anthropic's current practices and denied that it was already cutting corners; his criticism concerns the competitive race and the pressures he expects it to create. Responses dispute the evidence and timing of catastrophic-risk forecasts, whether continued work inside AI labs can be justified, and whether governments should pause development or regulate its continuation. The record distinguishes these disagreements from arguments about the rhetoric of public warnings.
