I always thought it's a strange arrangement that everything is hooked on these big, stupid batteries called stars, and everything must work toward efficiency, which increases complexity, which increases energy consumption, thus entropy.<p>To me this looks more like a death spiral than a simulation, with a curious by-product, stateful arrangement of particles whose state must be predictive of the future to be able to thermodynamically efficient and the other way around, and thus life is an obvious by-product of the spiral. It's just not an important part. A simulation implies importance, our Universe implies utter unimportance. I think that's why the simulation narrative is desirable. Who likes to be utterly unimportant? This is a psychological thing. With that you can put simulation to the same pile where deities and other antiquated beliefs are. Can't prove that it's not true, but can prove that we have a motive to think it's true.
