I think quantum physics and 'simulated reality' are one in the same. What's the difference between a reality which is only real when observed, and a reality which is only real when switched-on? What is the difference between a reality in which such reality is deterministic (ie. no free will (at the microlevel)), and a reality based on a pre-progammed algorithm?
