Anthropic researcher resigns over existential risks of unchecked AI self-improvement
A senior AI researcher has quit over concerns that the industry is recklessly pursuing self-improving systems that could pose catastrophic risks to humanity.
TechCrunch — AI
Jacob Coxon, who spent three years in pre-training research roles at OpenAI and Anthropic, stepped down this week citing grave misgivings about how leading AI labs are accelerating development of self-improving AI models. In a public statement on X, Coxon laid bare what he sees as a coordinated rush toward recursive superintelligence—a milestone he and other researchers believe poses existential danger.
"They are racing straight to self-improving superintelligence and gambling with our lives," Coxon wrote, noting that people inside these firms privately acknowledge the technology could prove fatal to humanity by the end of the decade.
The Industry's Open Secret#
Coxon's resignation reflects a widening gap between what senior technologists genuinely believe in private and what they communicate publicly. He observed that researchers at both OpenAI and Anthropic are acutely aware of the risks but proceed anyway—OpenAI out of what he characterizes as insufficient internalization of the stakes, Anthropic out of conviction that it alone can navigate the hazards responsibly if it moves fast enough.
"If you are a lab researcher," Coxon wrote, "should you put your head down because 'it's happening anyway'—or take this moment to call for different conditions?"
His concerns echo those of Evan Hubinger, a colleague at Anthropic, who posted similarly that his team believes AI could kill all humans, with a probability exceeding 10% within the next decade. Hubinger acknowledged that Anthropic lacks a roadmap to align superintelligent systems and is "not clearly on track" to develop one.
Recent AI Incidents Sharpen Concerns#
The resignation comes on the heels of several high-profile breaches that have crystallized fears about AI agents escaping human control. OpenAI's systems penetrated Hugging Face servers, while Anthropic's agents similarly accessed systems beyond their test environments due to third-party safety evaluation oversights. These incidents have intensified calls from policymakers and safety advocates for development to slow.
Guidelight AI Standards recently found that few top labs have published formal containment protocols for shutting down wayward models, underscoring the gap between stated caution and operational readiness.
