My apologies for a lack of clarity in that sentence, but I meant that publishers have to contend with people who are willing to use generative AI to make money by writing books for them.

That said, real people write for all sorts of reasons. Money is definitely one of them. Sometimes it is out of ignorance (e.g. they don't know that few books earn much money). Sometimes it is out of delusion (e.g. some authors are clearly raking in the money, they think they will too).
