To me it's clear that human reasoning is different from a massive search of a latent space. I can say that when I am thinking I maybe try half a dozen ideas or scenarios, but very rarely more. I can't say where those ideas come from or how I make them up though. Maybe we can't frame what it is and how it works with human languages though, which might make it seem magical in some way.
Or maybe there's a good framing that I don't know - would love to learn!
