Like most of these get-rich-quick schemes, there's probably no money in actually doing it, but lots of money selling "courses" supposedly teaching people how to make money day trading or betting. You don't even need to rent a supercar and a mansion for your photoshoot anymore, just generate some images "proving" your success.
An AI could make money by writing and selling slop books online via Amazon or elsewhere like direct ebook sales. If the books were at least middling there would be an actual honest to god career there, especially for niches like fan fics and under served IPs.
Well, it's about as honest as repackaging tap water as mineral water, given that the fans could just prompt personalized stories of the same quality, but it's a career for sure. :)
