Not really to answer your questions. But a book came out a year ago and it covers the philosophy of simulation theory.

That is it explains the theory that our reality may be a simulation inside of a computer, and then re-establishes all major philosophical ideas from this premise. Ironically enough, a lot of philosophical ideas it arrives at are very similar to those proposed by religious philosophers.

The book is called Reality +. Good read if you like philosophy and think simulation theory is interesting.
