Nobody need Bitcointalk, but I get your point and you have right forum is to meet other people and communicate with other humans not with a robot.
But I  can almost guarantee you that you don't have anything to worry about, I highly doubt that people using AI will take over the forum, at least as so long we got the base-community here that not using AI and the good people that report users that using AI.
All creed to you guys that doing that, it's actually something I really appreciate and most important, it actually make the forum to the better, a lot!
