What if we remove the stigma of authors using AI. We say, have at it, use all the AI you want. What then? The market is still finite. The authors are still competing with each other. They will still have to be good at creating compelling books that people want to read. Will the whole thing just blow over and AI would be "just another tool" that authors use to get their work out?
AI destroys your writing voice. There are authors who I enjoy not only because they write a compelling story, but they do so in such a way that is lyrically enjoyable. Engineers fall into the trap of thinking that if the slop machine emits the Internet-average sentence to describe a character’s actions, then it will suffice for all audiences and works of literature. “Add more adjectives and flowery language” will only net you a novel that reeks of cheap perfume. I guess we’ve lumped all of this under “taste” these days, but that’s what the AI author lacks. Without it, it’s probably going to be fine for producing summer beach reads (which could be quite lucrative!), but it needs to escape the mean it was trained on to be a truly unique, compelling voice.
