Dismissing the fears that robots will come to dominate their creators, Hans Moravec of Carnegie Mellon argues that humans will literally become robots, "uploading" their consciousness and memories into their computers. Advanced manufacturing techniques, he says, will enable the creation of machines that will far surpass the dexterity of conventional mechanical manipulators and even human hands. Equipped with molecule-sized "nano-fingers," these devices will be able to create any physical structure, atom by atom.
