The Simulation Argument is an argument for the Simulation Hypothesis, although first proposed by Hans Moravec the concept was popularized in 2003 by Nick Bostrom's paper "Are You Living in a Computer Simulation?" where he argues that one of following propositions is true: "(1) the human species is very likely to go extinct before reaching a “posthuman” stage; (2) any posthuman civilization is extremely unlikely to run a significant number of simulations of their evolutionary history (or variations thereof); (3) we are almost certainly living in a computer simulation. It follows that the belief that there is a significant chance that we will one day become posthumans who run ancestor simulations is false, unless we are currently living in a simulation."
