The suggestion that such a hypothesis is compatible with all human perceptual experiences is thought to have significant epistemological consequences in the form of philosophical skepticism. The simulation hypothesis, which was popularized in its current form by Nick Bostrom, bears a close resemblance to various other skeptical scenarios from throughout the history of philosophy. There has been much debate over this topic, ranging from philosophical discourse to practical applications in computing. Simulated reality, by contrast, would be hard or impossible to separate from "true" reality. This is quite different from the current, technologically achievable concept of virtual reality, which is easily distinguished from the experience of actuality. This simulation could contain conscious minds that may or may not know that they live inside a simulation. The simulation hypothesis proposes that all of existence is a simulated reality, such as a computer simulation.
