If you’ve seen the movie, you’re familiar with the simulation hypothesis — the idea that reality is instead a sophisticated computer simulation, or a video game. We’re not organic beings, but characters that a vastly more advanced civilization created in an intricate computer program.
In 2003 Nick Bostrom, a philosopher at the University of Oxford and director of the Future of Humanity Institute, published aarguing that not only is it possible that we’re living in a simulation, it’s probable. He points out that we’re currently creating increasingly realistic simulations of our own world.
