Episode notes

I think novelty is like things surprise you, right? So it's a very passive thing. Novelty could just be surprised. Your model of the world was broken and not necessarily in a positive way. You've got surprise, which is basically, I'm surprised all the time because I don't read very much. And then when looking at literature properly and it's there. That's to the extent that you don't have full information. It's kind of the same. Maybe that's why aliens haven't come yet is because we're not correct enough novelty. Like there's some kind of a hierarchy of novelty in the universe.
