"To me it sounds dualist if intelligence is disembodied. If the substrate doesn't matter, only the functionality, then that sounds like there's something additional to the world than just the physical constintuents."

Off the top of my head, what the substrate is doesn't matter, but that there is a substrate does. Intelligence is the behavior of the physical constituents.

"So why is physics so heavily reliant on mathematics? Quite a few physicists think the world has a mathematical structure."

Because humans are very good at defining the rules when we need them? Because alternate rules are nothing but a curiosity even to mathematicians unless there is a use---such as a physical process---for them?

One of the problems with qualia, as a topic of discussion, is that I can never be entirely sure that you have it. I can assume you do, and rocks don't, but that is about as far as I can get.
