…Savage said, there are signatures of resource constraints in present-day simulations that are likely to exist as well in simulations in the distant future, including the imprint of an underlying lattice if one is used to model the space-time continuum.*
I especially like:
For example, Davoudi suggests that if our universe is a simulation, then those running it could be running other simulations as well, essentially creating other universes parallel to our own.
“Then the question is, ‘Can you communicate with those other universes if they are running on the same platform?’” she said.
A better Skynet – the simulation host becomes a strongly godlike AI when it’s universes start comparing notes.
