The glorious future of AI, whatever that may be, cannot replace humans - not too many humans. Otherwise, who would buy books, especially at a discount, from Amazon? No income = no sales. That will never change.
Indeed. Who would buy books in a world where an infinite supply of books - and music, and video entertainment - can be dreamed up by an app on your phone, tailor-made to exactly fit your needs and desires?
Who would need Hollywood when an AI program can be told "give me a book-accurate 30-hour presentation of 'The Silmarillion' starring a cast of overweight bald midgets" and after a seconds computation the opening scene begins to play? Who would need publishing houses when that app, after studying your reading habit and/or directly scanning your brain, can throw together novels that are so precisely perfect for you that the serotonin levels become dangerously addictive?
Forget about "yeah, but how can that possibly be profitable" because it won't need to be. Modern publishing needs to be, because there are people involved. AI-based writing doesn't have any humans in the loop. Someone could well create that AI as a *lark.* Someone could create it as a university project. Someone could create it as a way to torpedo the publishing business that constantly rejected his own garbage novels. Someone could create it as a pay-per-book service that spends a few years making the creator bank, but which then finally gets cracked by hackers and modified into a freeware system.
There's nothing special or sacred about fiction writing or writers. If they can be replaced with automation, they will be. And unlike plumbers who need to physically show up and turn a wrench, this could in principle all be done on your phone. *Any* job that today can be done remotely will be doable by AI soon enough. Writing, acting, accounting, teaching, therapy, preaching... no reason why these can't be done by machines on a screen.
