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.
If you are a fan of simulation theory, the most compelling evidence I've found was something I stumbled across after considering the hypothesis that if we are in a simulation and clearly can talk about it without the world ending, that maybe there's something in our lore that breaks the 4th wall like we see in games explaining more about the nature of the simulation.
It took only weeks to find something I've been researching over the past few years since that exceeded my expectations wildly.
For example, it was lost for over 1,500 years. The only complete copy was rediscovered in Dec 1945.
At that same time this happened, the world's first Turing complete computer (capable of simulating another computer) was first put to use at Los Alamos on figuring out the starting reaction for a fusion bomb, also in Dec 1945.
Fusion bombs, where two atoms are made into one, are much more powerful than fission bombs. Recently a fusion test in North Korea made news for literally moving mountains.
Here's one of the lines from the text (saying 106):
When you make the two into one, you will become children of Adam, and when you say, 'Mountain, move from here!' it will move.
I recommend saying it out loud and noting the potential pun around Adam/atom. The people following this text also legit were talking about atomism and indivisible points making up all things (they seem influenced by Lucretius's specific phrasing for discussing atomism from 50 BCE).
This barely scratches the surface of what I found with this text and tradition.
