The minimal explanation for what is going on still requires that something must hold the state of the universe and execute its transition function. This prime mover, the basic Turing machine ticking away in the void is a debt that freaks me out.

The simplest prime mover conceivable of generating our universe is one that enumerates and runs ALL algorithms in a round-robin manner. Unfortunately, that does not tell us anything about the laws of our universe.

Isn't it evident that the enumerator is the prime mover? How else would one explain that humans likely could have evolved in much simpler universes? The additional complexity can only be explained by assuming that universes of all levels of complexity are run in parallel.

I think it is pretty likely that a simpler universe would not work. You need stable gliders (particles) traveling through a well-behaved noisy lattice, a bunch of emergent forces, stable negentropy bubbles, spontaneous formation of autostabilizing adaptive replicators (cells)

What about fine-tuning arguments? Do you think they will be resolved once we find a much simpler underlying discrete structure?

yes. it is possible that a large superset of the observable dynamics exist, and the specific constraints we observe are anthropic
