Is Steve Mann a cyborg? The University of Toronto researcher says the term is not an accurate one to describe the wearable computers he uses and researches, but it presents some interesting questions.
Mann has been criticized for wearing computers that can record video and perform other functions that we are more used to seeing humans do than other people. And as bionics become more advanced, we are now implanting computers in our bodies instead to supplement or even enhance our native capabilities.
Cochlear implants (which are electronic devices) are now regularly used to give the sense of sound to somebody who previously couldn't hear. And a few weeks ago, Minnesota's Allen Zderad received a bionic eye that allowed the 68-year-old, who had a degenerative eye disease for 20 years, to see his wife for the first time in 10 years. So there are definite medical uses for some devices, but how far should we go?
