The best “server-side” anti cheat mechanisms online is streaming the game, and I am sure that eventually some talented developers are able to even write some aim bot (or more) for that.
Competitive games need a fully controlled environment. Doing it online with random unknown people should not be taken as serious as they currently do.
Alot about video games is not standardized. To be competitive all players should have the same hardware, internet connection, etc. So that it is actually individual skill that is measured, not just the size of players wallet.
But even then, developing skill takes alot of practice and time, which also, in our current system, can be converted into money. There just is no fair competition here anyway. Still many people believe in meritocracies…
Streaming the game is never gonna be viable for me because of where I live, even if I wanted it, and I very much don’t. But then I don’t care for the kind of competitive games where what hardware you run on makes that much difference, anyway.
I don’t think we need “the best”. Just to be able to detect and ban the egregious offenders would be enough.
I will say we agree on one thing; competitive games should not be taken as seriously as they are. But then I’m of the controversial opinion that esports made gaming worse.
