Bruh, the LLM has parsed the entirety of Zork, plus maybe thousands of articles written (by humans) on it. At least pick a better example.
I would have to come up with something no human has ever conceived of. I don't think that is possible, or what point it would make, since nobody would be able to assess the quality of the output in that context?
Is it? The names might possible be original, and maybe the exact flow of ideas, but it's insanely rare for someone to come up with a new concept and not an amalgamation of existing ideas.
