Well, I'm saying the possibility is worth considering. I'm hardly going to claim certainty in this area.

As for QM...

The metric I think makes sense is, roughly, observer-moments divided by CPU time. Simulating QM takes exponential time, yes, but there's an equivalent exponential increase in the number of observer-moments. So QM shouldn't have a penalty vs. classical.

On the flip side this type of prior would heavily favor low-fidelity simulations, but I don't know if that's any kind of strike against it.
