Realism about rationality

I disagree that intelligence and rationality are more fundamental than physics; the territory itself is physics, and that is all that is really there. Everything else (including the body of our phone knowledge) are models for navigating that territory.

Turing formalised computation and established the limits of computation given certain assumptions. However, those limits only apply as long as the assumptions are true. Turing did not prove that no mechanical system is superior to a Universal Turing Machine, and weird physics may enable super Turing computation.

The point I was making is that our models are only as good as their correlation with the territory. The abstract models we have aren't part of the territory itself.
