Authors tell stories they want to tell and Readers read stories they want to read. The two don't necessarily overlap or overlap strongly enough. If you're even a little bit specific (nowhere near as specific as the above prompt, even just something like the dynamic between protagonists) then you don't actually have 10,000s of actual human written books. Not even close. Maybe it exists and maybe you'll find it good enough but if it's only been read by a few hundred or thousand people ? Good luck getting it recommended.

I've read a LOT of fiction. I love reading. And if it's good enough, the idea of reading something created by a machine does not bother me at all. So of course i will continue to see if the machine is finally good enough and i can be a bit more specific.
