I have criticized it for it's seeming lack of predictive power - a problem with all theories of everythingism so far, and also string theory.

That is a technical issue only. As comp has to predict or re- predict all of physics, it is hardly not predictive. In particular, comp + Theaetetus already provide the logic of the observable, and up to now, it fits with the facts.

Well it's no good saying it *must be* predictive - if it's true.


That is the non trivial consequence comp. It is the sense of "deriving physics from arithmetic". All rules of prediction about the observable reality *have to* be theorems in arithmetic, concerning bets by universal machines.



One can say that about many theories - including string theory.

OK. But string theory like QM have been build for doing that. Comp is just the idea that the brain is a machine, and the consequence is that the laws of physics are given by the relative measure on universal machine/numbers states.

With comp, physics = the laws of the universal machine observable, with observable defined by an indexical (like []p &p, or the others, p sigma_1 proposition).
