Simulation theory says that we are all likely living in an extremely powerful computer program, directed by an entity outside of our physical comprehension. In this situation, humans are not necessarily “real” and tangible beings, but instead predetermined, coded constructs of the digital world we inhabit. Living in a simulation can be likened to living in a gigantic game of The Sims, except we ourselves are the characters inside the screen.
If we live in a computer simulation, then who is the programmer? Swedish philosopher Nick Bostrom contends in his 2003 paper “Are You Living in a Computer Simulation?” that future generations might have mega-computers that can run numerous and detailed simulations of their forebears, in which simulated beings are imbued with a sort of artificial consciousness. Odds are, we are products of that simulation, and we may not be the original species of humans.
