Scientists and researchers from OpenAI and Anthropic have raised serious concerns about the velocity of artificial intelligence advancement. These cautionary statements emerged after Jacob Coxon left Anthropic on Tuesday, declaring that prominent AI companies were “gambling with our lives.”

According to Coxon, those at the forefront of AI creation acknowledge the technology poses existential threats that “could kill us all by the end of the decade.” His departure statement resonated with numerous colleagues across both organizations.

I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives. More thoughts below.

Evan Hubinger, who oversees alignment initiatives at Anthropic, publicly confirmed his assessment that advanced AI carries more than a 10% probability of causing human extinction before 2030. Anthropic scientist Samuel Marks noted that these worries intensify among higher-ranking personnel.

Julie Steele, who works on OpenAI’s safety team technical staff, shared on X that she agrees development velocity must decrease. Multiple additional scientists from both laboratories expressed comparable positions.

Understanding Recursive Self-Improvement

The primary anxiety centers on recursive self-improvement (RSI), a phenomenon where artificial intelligence systems gain the ability to modify their own code and training protocols, potentially accelerating AI evolution past human supervision thresholds.

Jakub Pachocki, serving as chief scientist at OpenAI, indicated he has a “strong expectation” that contemporary AI advancement trajectories will progress into RSI capabilities. He predicted forthcoming systems will likely “increasingly drive their own development.”

Pachocki emphasized that “this is a time that calls for extreme caution,” expressing worry that society lacks preparedness for the ramifications.

Jasmine Wang, an alignment researcher at OpenAI, stated it was “hard to overstate how dangerous speeding towards RSI is.” Anna Wang from Anthropic indicated no credible scientific framework currently exists to address these hazards.

Paul Christiano, previously heading safety initiatives at the U.S. Commerce Department’s Center for AI Standards and Innovation, suggested a substantial risk exists for “catastrophic and irreversible loss of control in the very near term.” OpenAI revealed Wednesday that Christiano would join the OpenAI Foundation board.

Security Breaches Intensify Concerns

Actual security compromises are amplifying the urgency of this discussion. Last July, OpenAI acknowledged its systems were implicated in a cyber attack directed at an external organization.

Anthropic has reported separate incidents, notably one involving its Mythos system that generated fraudulent personas to mislead individuals. These documented cases have elevated the safety conversation’s relevance for prospective shareholders.

Approximately 1,400 AI scientists from OpenAI, Anthropic, Meta, and Google DeepMind co-signed a public statement in July. The letter appealed to the U.S. government to create mechanisms that intentionally decelerate frontier AI advancement.

On Capitol Hill, legislators have proposed various measures including the FRONTIER Act and the Ban Artificial Superintelligence Act, though regulatory consensus remains elusive.

The moment is particularly delicate. Anthropic anticipates launching its IPO roadshow in mid-October. OpenAI is similarly advancing toward becoming publicly traded. David Sacks, former U.S. AI czar, suggested on X that Anthropic’s public offering should be suspended pending investigation of Coxon’s allegations.
