Not necessarily. A theory of everything does not imply either the computability of a future state or determinism.
Even if our ToE is deterministic the universe may be computationally irreducible, meaning it cannot be computed accurately at lower resolution in all cases. Note that such a universe could contain within it regions that are computationally reducible, just not the whole and not all regions.
I would expect a ToE to give us knowable bounds to either determinism or computability. It should tell us what is precisely knowable or predictable and what isn’t.
Edit: to understand how a ToE could leave some things unknowable (but tell us what they are) consider the Hubble horizon. Light beyond it will never reach us making sufficiently distant things unknowable.
Limits may be great. It means we can at least subjectively consider ourselves as having free will — even with a deterministic theory it may be unknowable determinism. It’s just like how the speed of light might be why we got to evolve before being bum rushed by aliens.
- FrustratedMonky 2y ago"cannot be computed accurately at lower resolution" The Map is not the Territory. Our universe is the lowest resolution. So to compute the next instant in our Universe, would need another entire Universe. We could be the computation occurring.
- api 2y agoThat’s what I meant, but perhaps did not describe well.
- FrustratedMonky 2y agoSorry, I was really just re-stating it, to see if I was grasping the point.
- goatlover 2y agoThe entire universe could be the quantum many worlds (branches in higher dimensional Hilbert space), and you would have to compute the wave function of the universe.
