You think LLMs will put authors out of work? I certainly hope not, given the quality of product they currently produce. If they produced genuinely creative and interesting work it'd be more likely and I wouldn't really mind, but there's no sign of that so far. We are so so far from LLMs competing with humans in writing anything longer than a few paragraphs.
Only a moron in a hurry would think that the output of LLMs currently can replace human authors spending a few years writing a book.
