Sherry Turkle, a professor of sociology at MIT, has for years been studying the way computers fit into people's lives.She points out that the computer, because it seems to us to be so intelligent,so capable, so...human, affects the way we think about ourselves and our ideas about what we are. She says that computers and computer toys already play an important role in children's efforts to develop an identity allowing them to test ideas about what is alive and what is not.
"The youngsters can form as many slight differences and textured relationship with the computers as they can with people."Turkle points out.
