Robots have been developed to replace humans in extreme or toxic environments and facilitate high-precision or repetitive tasks such as microsurgery or parts assembly. Robotic prostheses can be attached to bodies and increase human strength, give back mobility to the physically impaired, and we may soon be able to control or communicate with them by thought alone. In 30 years we have gone from mainframes occupying entire floors to computers in our pocket. With all the associated advantages of diminishing parts and technology costs, robots will no doubt experience an analogous development curve. In fact, a Russian media tycoon is personally financing research to overcome human mortality within the next 30 years (2045 Initiative) by developing “avatars” (humanoid robots) in which to digitally house our consciousness downloaded onto an artificial carrier, a concept that has made even the Dalai Lama enthusiastic.
