This is it. I know of too many companies (in nonfiction, specifically) trying to offload as much as possible to LLMs, damn the quality. Zero chance I buy any nonfiction written after 2021 or so unless it comes with strong recommendations from sources I trust. No more on-a-whim purchases because something looks interesting and is on sale or whatever. That’s over.
But even before LLMs, how many of those nonfiction books were any better than an assembly of random blog snippets?
Damn few of them.
I'm thinking the "industry" will contract a lot, but there will always be a niche for deep "real books" on a subject. It will just be much smaller.
