What is Reality

Not exactly Matrix, more like SimCity.

"Dr. Bostrom assumes that technological advances could produce a computer with more processing power than all the brains in the world, and that advanced humans, or “posthumans,” could run “ancestor simulations” of their evolutionary history by creating virtual worlds inhabited by virtual people with fully developed virtual nervous systems. "

Doesn't really change anything though; it's real to me, to us, irrespective of a Prime Designer, or not.
