@arteteco Have you considered how messy it would be we lived in a simulation?! We'd be back to the infinite-regress thing because how would we know our simulation was the first, because in all likeliness we wouldn't be. See, even being an atheist is not that relaxing! ;)
@QuentinMann It is pretty much guaranteed we are in some sort of a simulation. Its just a question of what type. It more than likely doesnt look anything like the sort of computers we imagine as the host universe likely has completely different fundamental laws.
