Yeah, frankly, this doesn't make sense to me. Has the author checked any nonfiction categories on Amazon recently? In many categories, 80-90% of all new releases are obvious AI slop. And even for non-self-published releases, about 20-30% previews get flagged as AI by Pangram, compared to roughly 0% pre-2023.
I don't buy (new) nonfiction because it now feels like playing Minesweeper.
