Fiction books to follow soon? Will kids still sit down and read an assigned book when they can just prompt "generate a movie of Shelley's Frankenstein, faithful to the source, except as required by my_movie_preferences.md". Reading the text may become as rare as learning ancient Greek to read the Odyssey.
You say soon but what you just described is still sci-fi as far as I can tell.
"Self-help nonfiction" have always been a waste of paper. And honestly, most of the time I hear "X was replaced by AI" I find myself thinking "good riddance, but we could drop X altogether and not loose anything of value."
Fiction, on the other hand… Much of fiction's value isn't just the content itself, is that they create a shared language medium. A book might actually be meh (came up with some examples, but then decided to drop it so as not to offend anyone), but the fact that people you talk with have read the same book and understand same references makes reading it valuable. So, it's unlikely to happen, until we delegate all of our communication to AIs, which isn't likely to happen any time soon.
"Luke… I am your father."
"…You're absolutely right!"
