> A fun experiment but LLM generated stories will never escape the uncanny valley, because they're not novel, they're remixes

Kid's books aren't intended to be novel. It's not like a four year old is going to say, "Man, this is a retread of Hamlet!" They are often re-tellings packaged up in a new way to appeal to kids in the current generation. Sometimes as simple as removing sexist, classist, and/or racist elements.
