Not sure I agree about the overall information complexity, since a first principles physics simulation of a universe involves simulation of all the wave/quanta up through molecular dynamics and on to macroscopic behaviour of the universe (and us in it)…

It’s hard for me to imagine the “information complexity” we’re inducing into the universe as significant compared to the total size of the state machine representing all the neutrinos and photons in the universe, let alone the other particles.

Also if the the universe is a simulation it makes sense the simulators would be working with snapshots since even if you have the computational capabilities to simulate an entire universe, you probably don’t want to waste whatever time/energy resources exist in the simulating universe, simulating the first few billion years till your simulated universe gets to the point you’re most interested in, be it changing parameters / picking the outcome of particular random outcome or just zooming in and studying what goes on in the randomness, or just looking at it like some kind of highly advanced virtual zen garden.

So I’m not entirely convinced that our electronic computation devices which operate by way of the movement of electrons or photonics devices operating by manipulating photons (and usually electrons too), represents our hypothetical simulators having to design or run a simulation of anything beyond what we call “normal operating behaviour of clumps of solid baryonic matter”. All the computers in the world, full of electrons and interconnected by fibre optic lasers, is unlikely to involve simulating more electrons, neutrinos, and other subatomic particle interactions than are necessary to simulate the earth’s inner and outer core and their electrodynamic (which are coupled to the solar electrodynamics) and thus simulate the production of the earths magnetic field.
