Sorry for taking so long to reply, I've had this on my mind for the past few days...
I like this theory and it is one that I've often pondered myself, that if we are in a sim, is it an alien sim or an advanced human one?
Let's go with it and say that it is indeed an advanced human one, if that is the case then the purpose of this sim/game would be impossible to know.
One theory I like is that it is part of a modelling experience to see how we behave in certain scenarios. Also maybe we have lived this life countless of other times. Kind of like the robots in Westworld, but with zero memories of our past lives.
Maybe there's no pause feature
Maybe so, however we would not be aware even if there was. Let's say that the 'player' pauses us for 10 subjective minutes. How would we know? To us the moment between pause and un-pause would be seamless.
Like pausing a game when the character is in mid air, and then un-pausing a few minutes later. To that character it has just been one continuous jump.
Maybe we are just preparing to upload the entire human race onto this computer and we are just checking its viability first :-)
I just hope our ability to be self-aware in this regard doesn't get patched away. I'll write about this now.
Did you see part 2 and part 3? I'll post part 4 later.
