The answer to this is solidifying reputation and filtering out the garbage from sources without a good reputation. The irony of this is that this is mostly idiots without a good reputation leveraging an AI that isn't much better in order to build a reputation so people take them more seriously. If you set it up properly, reputation is very hard to fake. You have to build it over years and you are dependent on other people with good reputations consistently up voting and vouching for your content. Every time you post something, you stake your reputation. AI can generate a lot of content fast; and some of it might even be alright; but unless it builds a reputation over many years, you can trivially detect it as coming from a source without any meaningful reputation. It doesn't matter how good or bad the content is if you slap a giant noob sticker on their account. All Stackoverflow needs to do is reset people's reputation to -1 if they get caught posting AI content. You don't need any fancy detection algorithms for this. And as the whole site is basically engineered around the concept of reputation, that shouldn't be too hard.
