This idea looks to me like an attempt to generate a new "proof" of the existence of God. If our universe is a 'simulation', then presumably there's an ontologically more real realm that it's a simulation of. A higher plane of reality. Heaven. And if our universe is merely a 'simulation', then presumably some cognitive and intentional agent exists that created the simulation, an agent who would effectively be omnipotent within the bounds of our universe, since he wrote its rules and can presumably violate them with miracles whenever he chooses.
