I would be surprised if we are not living in simulation. Look at superposition and function collapse in quantum physics, it's equivalent to what we are doing in games today = do not render if player is not watching, save resources. Think about it, look for example at GTA V, what we can achieve today and think about how world looked like 100 years ago.
I imagine that in 1000 years from now, simulating world similar to ours will not be a problem at all. Maybe not as complex because every level you go deeper you have less resources at your disposal. Who knows which level deep we are? Maybe we are simulation in simulation in simulation...
