It only dominates (and has dominated for basically the whole existence of internet chess) because games are short, fun, and non-committal. Playing a tournament game means spending hours on one game. That's exhausting and not something people "do for fun." On the other hand, you can get in a dozen 5 minute games in around an hour. Computers still overpower humans on 5 0 chess. Even a crappy non-optimized bot I wrote can get 12 levels of the tree plus quiescence essentially instantly.
