Regarding AI and God and religion - here is a blog post that I wrote that suggests that being in a simulation actually increases our chances for a religious afterlife.

If you transplant half your brain into another body, and both of you wake up, which one is you? If you start swapping your atoms one by one with someone else, and neither of you die, at what point do you become the other person?
Unfortunately questions like that are necessary in order to address the idea of a simulation afterlife. If our bodies are literally who we are, and our bodies disperse, it may not make sense to say that we can still be simulated after our bodies disappear.
Bostrom doesn't assume that.
