Watch some of the games and it might change your opinion. The thesis that "AI in Starcraft will only win via improved mechanics" is false - the AI was making some fascinating decisions / fundamentally different meta strategies.
Or watch [this game](https://www.youtube.com/watch?v=vUfwb4nOL84) between the top StarCraft AI (outside of AlphaStar) versus Serral, one of the top humans players. Unlike AlphaStar, this AI is not APM-limited; IIRC the top bots tend to play with about 100,000 APM, compared to 400 for the top humans. Serral won easily, despite the AI's vastly better mechanical skill.
