The Simulation Argument is a thesis set out in a 2003 paper by Nick Bostrom, a Transhumanist philosopher, in which he argues that the scenario depicted in the film The Matrix is correct, and that the world that we see around us is merely a computer simulation.
This paper begins by arguing for the logic disjunction between the following three propositions propositions:
- The human species is very likely to go extinct before reaching a "post-human" stage;
- Any post-human civilization is extremely unlikely to run a significant number of simulations of their evolutionary history (or variations thereof);
- We are almost certainly living in a computer simulation.
The paper then goes on to argue that as there is a significant chance that we will one day become post-humans who run ancestor-simulations, therefore it is almost certain that we are living in a computer simulation Since 2003 there has been a lot of interest in the idea, especially with the online community.
