I’ve never read books, but AI is corrupting the internet and can even rewrite online books, so I’ll probably start going to libraries if I want to see the human soul.
I guess you have to rely on books written pre-2021, as nothing stops authors (or publishers directly) to let AI generate text for their Books, and even train them to write based on sell counts…
Yes, it’s difficult, so we should have created libraries ourselves and stored books there to avoid this.
