This reminds me of a science fiction setting in which the human race basically halted all media production because an AI was created that scanned pieces of literature to see if any passages themes, characters, or plot points were based on anything from a pre-existing work owned by a major company. Which basically everything is going to be because absolutely nothing is ever created in a vacuum.

So no one could write anymore without facing a major lawsuit and having an AI basically tell the judge that you're guilty as fuck
