Book excerpt: Now available for the first time in America, I, Cyborg is the story of Kevin Warwick, the cybernetic pioneer advancing science by upgrading his own body. Warwick, the world's leading expert in cybernetics, explains how he has deliberately crossed over a perilous threshold to take the first practical steps toward becoming a cyborg--part human, part machine--using himself as a guinea pig and undergoing surgery to receive technological implants connected to his central nervous system. Believing that machines with intelligence far beyond that of humans will eventually make the important decisions, Warwick investigates whether we can avoid obsolescence by using technology to improve on our comparatively limited capabilities. Warwick also discusses the implications for human relationships, and his wife's participation in the experiments. Beyond the autobiography of a scientist who became, in part, a machine, I, Cyborg is also a story of courage, devotion, and endeavor that split apart personal lives. The results of these amazing experiments have far-reaching implications not only for e-medicine, extra-sensory input, increased memory and knowledge, and even telepathy, but for the future of humanity as well.
