Well, yes. There is no end of clever things you can do to optimize your
physical-layer computers. But none of this requires that you have a VR
anywhere, or works better with a VR than without.

I'd be wary of doing that, since the numbers wouldn't actually be random.
Though it does lead me to wonder what kinds of subtle defects might evolve
in a simulation that used its own data as a pseudorandom number generator.

"Captain, ontological engineering reports a new level of hidden meaning has
emerged in computation node 4. They project that virtual life forms will
emerge any second now, and sentience may evolve in as little as six hours!"
"Damn! We should have taken time to randomize at that last galaxy. Now we
have to revert to backups and reinitialize the bit store."
