It's true, it just might not mean what you think. "Quantum supremacy" = "This circuit runs faster than it possibly could have under classical rules, no matter how clever it might be," aka. an asymptotic speedup. It proves that quantum computation is possible, and the universe isn't just conspiring to pretend quantum mechanics works while actually following something like Copenhagen, but few people were doubting that in the first place.
