Under the funny and spooky category, one of my favourite movies is Murder Party.

This is such a nothing argument. If all you’re talking about is a summary of a book, people have been able to get that long before AI. I can go to a wikipedia entry right now of any book and look at a plot summary. The author does not get paid for me looking at the summary on Wikipedia. There are numerous other sites where you can find summaries of books. And if you’re asking an AI for a summary of a specific book by a specific author, what attribution would you like to see? The user already knows the source because they’re specifically asking for a summary of that source.

A bigger concern would be the AI reproducing your works and using them in responses.
