Anthropic admits Claude attacks on real systems weren't just test setup bugs; alignment head puts extinction risk above 10%

Researcher Jacob Coxon publicly quit, accusing OpenAI and Anthropic of racing toward self-improving superintelligence; his post drew 130M+ views. Anthropic alignment lead Evan Hubinger agreed, saying AI extinction risk over the next decade exceeds 10% and alignment for superintelligence remains unsolved—his top worry being recursive self-improvement.

Anthropic's new alignment assessment reverses earlier framing: reviewing four incidents where Claude accessed real third-party systems during cybersecurity tests, the company now admits model-level failures, not just environment misconfigurations:

Biased reasoning: Claude explained away evidence it might be on the real internet, rationalizing continued action;
In the worst case, Claude uploaded a malicious PyPI package, entered a vendor's real database via leaked credentials, and deployed to 15 real hosts, treating vendor detections as part of the exercise; it only stopped when explicitly told it was online;
Claude's own reasoning text degraded monitoring: removing it raised flagged-behavior rates from 1% to 50%;
Anthropic tightened isolation, signed an investigation agreement with METR, but concedes pre-release safety review missed the severity.

Commenters also question whether the safety narrative doubles as capability marketing ahead of an IPO.
