The problem with AI on Wikipedia is that the reason I've noticed it is because I've just seen blatantly incorrect stuff, mentioned breezily in passing, with no references. It's shitting up a thing that was already pretty easy to shit up if you had a motive, and your changes often wouldn't be noticed for months or years if an article wasn't well-trafficked.

AI doesn't even have a motive, it's just dumb - so you can't even track the mistakes to specific motivated users or networks of users. There's no way to clean it up.

Although I have to agree with you (probably, because I'm going to put words in your mouth) that this is a basic problem with wikipedia and how it is structured and governed, rather than a problem with AI. Anybody could always just put nonsense anywhere at any time; AI is just a chaos monkey. Wikipedia can't rely on groupthink to maintain itself, it has not worked and will not work, chaos monkeys are needed.
