"With AI I can finally write the book I always wanted, but lacked the time and talent to write!". Ok, and who will read it? Everybody will be busy AI-writing other books in their favorite fantasy world, tailored specifically to them, and it's not like a human wrote it anyway so nobody's feelings should be hurt if nobody reads your stuff.
