Even accounting for my sloppy shitty mistakes i probably made in this highly scientific study, it seems to take a whole lot longer to simulate one second of the universe than what it takes for the universe to pass one second. And this does not even considering the constant expansion of the observable universe (which, undoubtedly, expands faster than Moore's law). Therefore, simulation theory is now, and always will be, a religious fable with no basis in reality.
