Honestly, we're seeing it most in sub-industries (romantasy especially) where authors are under pressure to put a book out at least every quarter the churn in some genres is impossible. Fortunately I work in YA and NA (diving into an adult dark fantasy novel next actually) and there's a LOT more leeway to put a book out every couple of years instead of every couple of months. But knowing what I do about how generative AI works, I won't let it anywhere near anything I work on.
The nut punch about the most recent author who got caught? She asked it TO WRITE LIKE A COMPETITOR. So it mined pirated books to mimic her competition to rewrite some of her work. If that's not next-level ethically bankrupt behavior I don't know what is. That's tech inventing ways to be unethical. (The ironic thing is most working writers I know actively avoid reading authors they like while working so that they don't accidentally ape their style and here was someone asking a computer to do it for her. Wild stuff, man, wild stuff. I've lived too long, I swear.)
UNRELATED to the nightmare of AI in publishing, I'm reading Joe Abercrombie's new book, "Devils," and he's still Joe Abercrombie. Which is a good thing. Readable as hell, funny AF, some of the cleanest, best action sequences in grimdark, a crew of misfits who are likable when the world would prefer they weren't.
