The universe functions because all the rules are in place. But predicting the outcome of those rules without actually "replaying" them may be impossible. Example 1: Conway's game of life. Example 2: Collate conjecture. If the number is even, divide it by two. If the number is odd, triple it and add one. The rules are deterministic. But you can't do any predictions other than running the simulation.
