It ushers in a golden age where Alekhine-style positional sacrifices are not as refuted as we had once thought, and that the horizon effect is alive and well for Stockfish at least. I think it's a golden age of chess where even a beginner gets an instant reality check about their ability, unlike the past, where someone who "beat their friends" thought they were international strength. With shorter time controls, the execution of existing theory will replace the creation of new theory. AlphaZero has also shown there is an entire level of sacrifice above what anyone has ever conceived, and that it's actually sound. Would love to see what it does with the Jerome Gambit.
