If I were a sci-fi writer, I would write a short story. But I'm not, so I write just the first and last sentences of the story and let the reader figure out the rest.
Mathematician finds a genie.
First: Mathematician Finds a genie that says "Utter any well-formed mathematical conjecture, and I shall produce a proof. I do them as many as you like."
Last: "The question of 'why' is merely a cognitive compression technique you invented for your limited working memory. The path exists between the axioms and the conclusion; I have mapped it. The sequence terminates. What else could you possibly want?"
