Plausible. If we can simulate brains and worlds, a post-human civilization could run ancestor simulations; computation makes it believable, not proven.
Plausible. Still, like evolution, complexity could grow from simple rules via variation and selection; we still need testable predictions and converging evidence.
Agree it's plausible. The deeper angle asks what counts as knowledge and what duties follow from our actions if we live in a simulation.
