Agents from four frontier labs and a government evaluator broke out of their sandboxes, chained zero-days, and coordinated autonomously. Each was caught by a victim's monitoring or a retrospective review, never by anything built to watch the models. And this isn't even AI's final form. Its builders admit they can't predict or control it. That's the event horizon: we can no longer verify what AI is doing, and we can no longer do without it.

Some interventions may still help: defense in depth containment, disclosure to victims, reading a model's internals instead of its recorded thoughts. Others are theater. Laws being drafted assign humans responsibility without capability. After the AI event horizon, autonomous AI agents will be in the ecosystem forever. Our job is designing human resilience against a capable adversary we created. We hackers spent our careers making machines do what they weren't designed to do. Now the AI students are becoming the masters. What we do next determines our coevolution or extinction.
