One thing that seems missed in this simulated world idea is the question of resources required to run a simulation of an entire world. How many atoms of silicon and how many electrons of electricity are required to run a simulation of an entire world? Is there enough matter in the universe to run a single simulation that is as complex as the universe itself? Sure, if space is infinite, you could theoretically pull together the resources to do it, but how likely is it that all of those resources would be present in one spot. <br><br>Or, do you just have to assume that our simulation may seem complex, but the outside world could be more complex? Do we assume that the world outside of the simulation has different laws of physics that allow for simulating complex things in tiny spaces? Where is my logic off here?<br><br><br>Wait, no, he addresses it in the last half.
