The Simulation Hypothesis, first published by Oxford philosopher/physicist Nick Bostrom, speculates that in the future, our descendants could create computer simulations that would be indistinguishable from reality, and that we may be living in that simulation.
This video is a very high-level overview of the Simulation Hypothesis, here are some links that go much deeper:
