The Dream of Mechanical Life

The peak of all this may be the moment at which the inventor Ray Kurzweil asks, "As Machines become more like People, will People become more like God?" The infectiously enthusiastic Kurzweil is the leading proponent of "Strong A.I.," a brave new world in which a "Non-invasive Surgery-Free Reversible Programmable Distributed Brain Implant" will soon become available. In the keynote essay in "Are We Spiritual Machines?" Kurzweil imagines nanobots--hyper-intelligent miniaturized robots--zipping around our brains and downloading our mental software onto new hard drives which will somehow become re-embodied as us. Immortality looms, if "we are sufficiently careful to make frequent back-ups."
