But in a simulation, not in reality.

So you do (bad) theology. You talk like if we knew already what reality is. But with comp reality is anything Turing complete. So here you do an implicit metaphysical assumption, which is inconsistent with mechanism. No problem ... as long as you are aware of this.

I was being sarcastic, since Jason other places assumes simulation and reality are indistinguishable.

It is indistinguishable is the first person direct apprehension. But for someone able to test the statistics on its experiment outcomes, it is testable relatively to comp. If the physics does not conforms to the computationalist logic of the observable, it means that either classical computationalism is false, or that we are in an emulation à- la-Boström (to distinguish it from the infinite UD emulations). The already done quantum testings confirm a posteriori that we might live at the base "emulation" (by the UD or the whole of arithmetic). That base is not really emulable in the usual sense, as it is a sum on infinities of emulations in the UD.
