I don’t think it’s unfair to put some restrictions on the universes you want to describe. Sure, reality could be arbitrarily weird—but if the universe cannot even be approximated within a number of bits much larger than the number of neurons (or even atoms, quarks, whatever), “rationality” has lost anyway.
(The obvious counterexample is that previous generations would have considered different classes of universes unthinkable in this fashion.)

Why? If the universe has features that our current computers can’t approximate, maybe we could use those features to build better computers.
