1. GP didn't say that they could predict what will be "fast enough" they can predict what will be "slow". 2. A kind reading of GP would also understand that one is predicting what will be slow under some set of conditions. 3. Requiring 100% accuracy to call it a prediction is absurd. A weather forecast is definitely a prediction even though it's not 100% accurate. The NOAA isn't "guessing" weather in the general usage of the term "guess" 4. By your definition extensive benchmarking, measuring a program, and optimizing based on those results is wrong, because we don't even know if the end user will ever run the program!
