Simulated reality

Simulated reality describes a hypothetical environment that, although experienced as real, is actually a highly detailed simulation of reality. Unlike the currently technologically achievable concept of virtual reality, which is easily distinguished from the experience of "real" reality, a simulated reality would be impossible to tell apart from "real" reality. Hyperreality describes postmodern ideas regarding the perceptions of reality which in some ways parallel this concept.

Simulated people in simulated reality

Several people have pointed out that if a human brain is analyzed in sufficient detail, the mechanism of that brain might be electronically simulated. The result would behave as an electronic duplicate of the original human brain, as occurs in mind transfer. Whether the speed is similar to the normal speed of a brain would affect how it could interact with the real world. Gathering enough detail is neither possible nor practical, at present in the early 21st century. Science fiction authors have noted various difficulties which such a being may encounter, such as its existence being legally recognized, the right to own property, and the relationships with the original and other duplicates of itself.
