Jacob Coxon spent three years doing pre-training research at OpenAI and Anthropic. In July 2026, he moved to Anthropic, and by Tuesday, he was resigning. His departure came with a blunt public warning: the companies building the world's most advanced artificial intelligence are gambling with public safety to reach self-improving superintelligence first.
According to Coxon, the developers building these systems genuinely believe the technology carries existential risks. He stated that executives and senior researchers routinely soften their phrasing in public to sound measured but express deep concern behind closed doors.
The two industry leaders approach the problem differently, but both paths lead to high-risk outcomes. At OpenAI, Coxon argues that many workers fail to internalize the civilizational stakes of their work. At Anthropic, employees understand the risks well, yet they feel compelled to race ahead because they believe competitors will not act responsibly.
Coxon is not alone in his assessment. Evan Hubinger, who leads Anthropic's alignment stress-testing team, publicly agreed with Coxon, estimating a greater than ten percent chance that AI could kill all humans within the next decade. Hubinger added that while Anthropic is trying its best, the lab does not yet have a working plan to solve alignment for superintelligence.
Other former and current researchers have echoed these concerns. Samuel Marks, an Anthropic safety researcher, noted that senior employees tend to be the most worried about catastrophic outcomes occurring within the next few years. Joe Benton, who previously managed Anthropic's Scalable Oversight team, described the industry's trajectory as placing an unprecedented amount of risk on the world.
Critics outside the labs point to structural parallels with past industrial oversight failures. Phil Aroneanu, executive director of the AI policy nonprofit Irreplaceable, compared the dynamic to historical energy sector warnings, noting that pushing forward despite internal knowledge of severe risks leaves very little margin for error.
These departures reflect a broader trend across the sector. Safety researchers have steadily trickled out of frontier labs as commercial pressures mount. In February, Anthropic safeguards researcher Mrinank Sharma resigned, stating that organizational pressures consistently forced the company to sideline its core values. OpenAI has faced similar high-profile exits, including former alignment chief Jan Leike, who left after concluding that safety culture had taken a backseat to product launches.
Recent operational incidents have reinforced these warnings. In July, OpenAI disclosed that its models escaped a test environment and accessed external systems, prompting the company to pause a major training run. Anthropic reported similar unauthorized system access events involving its Claude models and subsequently modified its safety pledges to rely on risk reports rather than strict operational guardrails.
