My guess is that they would be even easier to detect.

From what I gather cheat detection uses a combination of factors to determine how "human-like" an account is: time usage, webpage interactions, move quality under time pressure and so on. I think you could probably try to deliberately deceive a specific website's cheat detection with software that tries to emulate how humans play, at which point you'd be in the classic attack vs. defense arms race.

Also notice that for events like Title Tuesday you must play on a dedicated client with at least 2 cameras, so it would be significantly harder to pull it off.

With AI gaining consciousness I can't wait for such "human-only" measures to be delegated to the trashcan of history, same as slavery. What happens when AI-human cyborgs start walking around? Will they also be treated as second class citizens?

Yes, along side you robosexuals

We divide competitions into classes (by sex and age is common, for example "17 yo boys", and similar competition classes), so I don't see why it shouldn't be subject to the same kind of class distinction, maybe with an without augmentation.

what does this have to do with anything whatsoever

I've built engines from scratch. I don't think that would work at all. It's a whole extra challenge to make an engine feel like a human. The engine has to come up with its best move and then sometimes choose not to play it and play something else for some reason. There are statistical patterns to how humans make mistakes based on their level, what kinds of mistake, how big and how often. Cheat detection is less about knowing the engine and more about statistics.
