Even if the universe is deterministic, its future is still unknowable, as in to predict the future of the universe you would need something to simulate every subatomic particle of all matter etc and so doing that computation would need something bigger than the universe.
I like to think of the universe as a deterministic computer that is calculating its own outcome - there is no shortcut to jump to the end.

I've mostly heard this dubbed "computational irreducibility" https://en.wikipedia.org/wiki/Computational_irreducibility https://en.wikipedia.org/wiki/Computational_irreducibility

- setr 9y agoIf there is no one to determine "correct" behavior, then there can be no bugs. If the universe crashes one day due to a mishandled null atom, we'll just have to take it as correct behavior (too bad for us!)
