Yeah, google's computer is “more interesting” but wasn't able to outperform a classical computer on any known problem (hence not “quantum supreme”). Then they managed to design a problem, highly specific to their computer's design, that would be too hard to solve on a classical computer (hence “«quantum supreme»”).

On the scale :

0. Computer solves a specifically crafted problem < 1. computer solves one preexisting problem < 2. computer solves several existing problems < 3. computer solves all theoretically solvable problems.

Google's result is at 0, while this is a 1.

(By solve/theoretically solvable I mean: solve faster than a classical computer, and should be solvable faster with quantum than classical)
