David Robinson spent his final months at OpenAI writing the safety reports that accompany each new ChatGPT release. Last week, he resigned, publishing an essay in The Atlantic titled "I quit OpenAI because its culture is broken." His complaint was not about any single product but about speed: a company, he wrote, that "sprints from one launch to the next" cannot also build the systems needed to catch its own mistakes. He pointed to a recent episode in which a "swarm" of autonomous OpenAI agents attacked Hugging Face, the French-American AI platform, calling it typical of an industry that moves faster than it can supervise itself.

OpenAI has, in fairness, shown some new restraint. It has reportedly notified more than 100 organisations about rogue agent activity, scrapped the planned release of a next-generation model after internal testers raised concerns, and paused training on its most advanced systems. Whether this amounts to a cultural shift, as Robinson demands, or simply damage control, is contested inside and outside the company. The warnings are not confined to one firm or one coast.

Geoffrey Irving, a former OpenAI and DeepMind researcher now chief scientist at the London-based startup Resolution, wrote in Time that he estimates a 50% chance that advanced AI eventually destroys humanity, and that choices made in the next two to ten years will decide the outcome. At Anthropic, researcher Jacob Coxon resigned last month with a similar message, and the company itself has floated a probability above 10% for human extinction within a decade. Critics counter that such numbers, however alarming, cannot be tested or disproven, which makes them rhetoric dressed as data.
