The line between a cyborg and an enhanced human is often blurred, but advocates on both sides of the argument have agreed on some generalities. A cyborg often sports prosthetics in addition to implants, and either requires them to perform their job or cannot survive without them. Cyborgs often feel a sense of detachment from their bodies. The humanity of a cyborg who has undergone a total body replacement (a TBRC) is contentious and poorly covered by legislation. In general, they enjoy the same rights as humans. In practice, people treat them like machines. One could argue that, with the pervasiveness of wrist communicators and noosphere interfaces, all non-cyborgs are enhanced humans, but the term is usually reserved for individuals, often wealthy, who have pushed their mental, physical, and sensory performance beyond anything that resembles human standard. Humans who have completely replaced their biological components with synthetic biologicals also fit into this category.
