Go on to Ao3 and a popular fandom, say like A Song of Ice and Fire: 9 out of 10 fanfictions written in the past two years stink to high heavens of AI. 9 out of 10. From some that are obvious AI to even normies, to some that slip one or two ai tropes after a couple of chapters, because the author got lazy and stopped editing carefully.

It's sad, infuriating, discouraging. A deluge of slop drowning the last embers of authentic human creativity.
