I think about this a lot, I think what if we are what does it mean... it means nothing..
and I go round and round thinking about it then I realise from our perspective it really doesn't matter, we feel we experience and we die and its over, whether that was part of something natural or simulated at the level we're at really doesn't matter.
You could say that it would be better if we were part of some computer simulation because at the end of it hopefully, the people in the tier above will learn something from the experiment.
Unless as is in Hitchhiker's Guide To The Galaxy they accidentally turn off the experiment 5 mins before completion in order to build a freeway!
