Perkowitz charts nearly 100 years of research into machines ranging from purely mechanical automatons to bionic parts for people. He looks forward to retinal implants A retinal implant is a biomedical implant technology currently being developed by a number of private companies and research institutions worldwide. The implant is meant to partially restore useful vision to people who have lost theirs due to degenerative eye conditions such as and brain-embedded computer chips that could alter a person's mental capacity and emotional states. Also featured are machines that rival human abilities. Perkowitz describes the controversy and ethical dilemmas An ethical dilemma is a situation that will often involve an apparent conflict between moral imperatives, in which to obey one would result in transgressing another. This is also called an ethical paradox that accompany them. Joseph Henry, 2004, 238 p., hardcover, $24.95. |
