"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.
