The version of the simulation hypothesis was first theorised as a part of a philosophical argument on the part of René Descartes, not firstly by Hans Moravec. Later, the philosopher Nick Bostrom developed an expanded argument examining the probability of our reality being a simulation. His argument states that at least one of the following statements is very likely to be true:
- Human civilization is unlikely to reach a level of technological maturity capable of producing simulated realities or such simulations are physically impossible to construct.
- A comparable civilization reaching aforementioned technological status will likely not produce a significant number of simulated realities (one that might push the probable existence of digital entities beyond the probable number of "real" entities in a Universe) for any of a number of reasons, such as, diversion of computational processing power for other tasks, ethical considerations of holding entities captive in simulated realities, etc.
- Any entities with our general set of experiences are almost certainly living in a simulation.
- We are living in a reality in which posthumans haven't developed yet and we are actually living in reality
