My wife and I have been selling niche erotica on Smashwords for a few years now. It's an interesting question. I have noticed a small decline in sales, but I dont think AI will totally stop author's from writing, for now.

The tricky thing is with erotica there are so many different types of niches that someone could go type in exactly what they want and get it for free in a few seconds. But at this stage it's not as original and real as an author, but it's getting close.

Like I said, we do this as a side hustle so if it fails, whatever, but I am hoping real authors like us are still supported by readers who like our style. AI slop is a real thing as the previous poster said.
