I've also used ChatGPT to poke fun of family members in a Dr Seuss style short story. Great laugh for the whole family as the short stories have been really good. And people love hearing their names in stories.
I think this gives more people tools to easily create books. Hopefully it improves literature. Much of the books I've read that have been produced in the past few decades have a lot of fluff. Same with video series on Netflix, etc... Plenty of stories created that don't add to character development or the story. Plenty of pages written that don't add to a non-fiction book's value but are meant to add pages to meet a publisher's criteria & come off worse than a college kid increasing font & line spacing.
It'll be interesting to see how these stories compete & which stories get the most recommendations & "authentic likes".
