How seriously should we take catastrophic-risk warnings when they come from people who worked directly on frontier systems?
This project began with a public resignation. Jacob Coxon said he had spent three years working on model pretraining at OpenAI and Anthropic, and that he left because he believed both companies were racing toward self-improving systems under unsafe conditions.
His context matters. Someone who worked close to frontier training may have observations the public does not. His conviction also does not make his forecast true. The post offered a warning and an argument, not a demonstrated path to catastrophe. The timeline, mechanism and probability remain deeply uncertain.
That tension is exactly what belongs on the clock. The claim is notable enough to raise concern, but too uncertain to treat as a verdict. We recorded it as +2: a meaningful signal, held at arm’s length.
We do not know if we are doomed. We do know that capabilities, safeguards and public consequences are moving faster than most people can follow. It seems worth keeping score.
