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.

Why critics condemn it
How this argument is supported
Coxon argues that the competitive race by Anthropic and OpenAI toward self-improving superintelligence is irresponsible, even though he praises Anthropic's present practices and denies it is already cutting corners.
Coxon argues that competitive pressure can force even a comparatively responsible lab to take risks that should not be chosen by private companies alone. Hubinger, Marks and Wang acknowledge unresolved safety problems. Sanders advocates a pause and ban; Elmore rejects remaining at a lab after acknowledging such risks. These positions support intervention or withdrawal for different reasons, rather than proving one particular extinction forecast.
Limit of this argument
Coxon praises Anthropic's current practices and denies it is already cutting corners. Several concerned researchers think continued safety work inside a lab can reduce risk, and disagreement remains about probabilities, timing and workable coordination.

““Many AI developer staff desperately want to slow down to figure out how to build AI more safely.””
His personal-capacity statement supports the central criticism but presents continued safety work as a conditional rationale for remaining at Anthropic.

Samuel Marks
September 9, 2026 · Anthropic safety researcher, explicitly writing in a personal capacity.
Addressed record
Samuel Marks said robust AI alignment remains unsolved, competitive incentives contribute to continued development, and many frontier-lab staff want a slowdown to improve safety.
““Many AI developer staff desperately want to slow down to figure out how to build AI more safely.””
Marks endorsed Coxon’s concern about the race and unresolved alignment while explaining that he works on safety at Anthropic to reduce the risk.
Classification rationale
His personal-capacity statement supports the central criticism but presents continued safety work as a conditional rationale for remaining at Anthropic.
Context before
Marks reposted Coxon’s thread with an explicit personal-capacity disclaimer.
Context after
He described commercial incentives, a perceived race with less responsible developers, and unresolved robust alignment.
