I saw a couple of interesting new tech books from Manning and Packt and they were AI slop that just appeared out of the blue. So I held off buying them. There is no guarantee that the authors invested the time in creating the tutorial,book or the course so why would I waste money on that?
Packt has been known to be slop even many years before AI. Very little proofreading / editing, authors rarely being well-known experts etc.
