No. My point is that computational complexity as understood in this universe depends on causality. Without causality, the logic falls apart.
If a universe is acausal, there could, potentially, be O(0) algorithms for basically anything. (I can just input a condition that terminates only if the answer is correct, and have the answer immediately based on the fact that it worked.) If so, the simulation could be instantaneous, and therefore any simulation would have the same cost.
My point is that it’s not very useful to know that a universe exists, if we don’t have a method for locating it in configuration space—and that method would eat the costs of causality, even if the universe itself doesn’t. Like in the GAZP.
