There's not really any need to speculate when this has already played out in other mediums - would you say that the proliferation of LLMs has led to an explosion of novel and interesting works of fiction, or just an explosion of cookie-cutter slop ebooks?

I would say too soon to tell. There has been an uptick in ebook slop, but I'm not sure if it's impacted the homogeneity of literature, because I don't think anyone is reading ai ebooks. It's not enough for it to exist to impact culture, it has to be being consumed.

Music is a uniquely interesting case, since music has a much lower barrier of entry to consume.
