The idea that we're living in a simulated reality, a real live Matrix, isn't new. It was notably popularized by the philosopher Nick Bostrom back in 2003, and has since been hotly debated by some of the world's best minds. Even Elon Musk thinks the odds are quite good that we are. Essentially, to oversimplify a bit, the theory is that the universe is so vast that other highly intelligent civilizations must exist -- ones with computing power that far exceeds our own, capable of running grand simulations. We may simply be the simulation of some civilization's ancestors, set up for entertainment purposes, or to run tests on the emotional effects of particular world events on our "artificial" minds. It's a bonkers idea to wrap your head around, but within the realm of possibility.
