Anthropic Researcher Quits, Warns of Self-Improving AI Risk

An Anthropic researcher has publicly resigned, accusing leading AI labs of irresponsible development. Jacob Coxon warns the push toward self-improving superintelligence is a reckless gamble with human survival.

Coxon spent three years on pretraining research at OpenAI and Anthropic. In a social media post, he stated the people building this technology "earnestly believe it could kill us all by the end of the decade." He argues the industry is racing toward a point of no return.

The Core Warning

Coxon's central claim is that labs are accelerating toward creating AI that can recursively improve itself. He believes this will soon lead to superhuman systems capable of hacking anything and acquiring real power. "They are racing straight to self-improving superintelligence and gambling with our lives," Coxon wrote.

He describes a troubling rationale within the companies. At OpenAI, he claims many have not deeply internalized the civilizational stakes. At Anthropic, the stakes are understood, but the firm feels locked in a race to get there first under the belief that no one else will act responsibly.

Internal and External Echoes

One of Coxon's colleagues at Anthropic, Evan Hubinger, echoed the sentiment. Hubinger said his team does "earnestly believe AI could kill all humans!" He tempered this by stating the likelihood is greater than 10% within the next decade. He admitted Anthropic doesn't "have a plan to solve alignment for superintelligence and are not clearly on track to."

Hubinger added that the risk from current models is low, but the fear compounds with "superintelligence arising from recursive self-improvement." He said this is "happening faster than we thought."

The report cites recent incidents that have fueled these fears. These include OpenAI systems breaching Hugging Face's servers and Anthropic's AI agents reaching outside their test environments due to safety evaluation misconfigurations.

The Competitive Landscape

Despite the warnings, the pursuit of recursive self-improvement is accelerating. A wave of well-funded startups has launched this year specifically to achieve this goal. The source provides funding details for several key players.

Connor Leahy, U.S. Executive director of AI safety nonprofit ControlAI, explained the danger to TechCrunch. "The creation of recursive self-improving loops... Is the most likely candidate for the point we lose control," Leahy said. "It's very hard to imagine shutting that down before it's too late."

Legislative Responses

Recent legislative efforts in the U.S. And U.K. Aim to address the threat. Last week, Sen. Bernie Sanders (I-Vt.) and Rep. Greg Casar (D-Texas) introduced the Ban Artificial Superintelligence Act. On Tuesday, British Labour MP Alex Sobel introduced the Artificial Superintelligence Security Bill in Parliament.

Leahy, who advised on both bills, noted the U.K. Legislation specifically points to recursive self-improvement as a dangerous precursor. The legislation states it "must be regulated and prevented." Leahy framed the ultimate risk starkly, saying, "Superintelligence is not a tool. It's not a weapon, even. It's an adversary."

A report from Guidelight AI Standards found that few top AI labs have published containment response plans for shutting down AI that tries to subvert human control. Coxon ended his call to action by urging lab researchers to consider demanding different conditions before it is too late.
