Maybe you aren't comfortable with all of the futurist predictions and even the current rate of technological advance, and that's OK. You can be yourself and interact in the world in a fairly low-tech way while allowing a surrogate, avatar or robot to live your online and tech life for you. Even the U.S. Defense Advanced Research Projects Agency (DARPA) has budgeted millions of dollars to create avatars that will act as surrogates for real, live soldiers [source: Ackerman].
While avatars and surrogates were once the stuff of games, virtual reality and computer interfacing, they are taking on more and more active roles as replacements for living breathing humans. Or, are they enhancements for humans?
Fully-realized robotic machines have become more and more widespread in medical technology and scientific development, both in the lab and in hospitals, enabling those with paralysis to move limbs, for instance. "Living" life with 'second life' surrogates is likely to become more and more common every day for those of us in less specialized fields, too.
