I know there are already people working on creating AI filters, to filter out spam articles and other AI-created content.

These will probably (ironically) be largely labeled by AI. As in, you get an AI to detect AI text and content generation and flag those websites as likely AI generated, with some kind of scaling probability index. That said, I think you could use AI to enhance human writing and that's fine. Maybe write something on your own and then have an AI restructure it or reword things for clarity, fixing grammar mistakes and other things. But full on "write me an article on [insert random thing here]" is where shit gets tedious.
