Robo-legs: more human cyborgs

A man has three sets of legs: one for walking, one for running and one for swimming. Another plugs music straight into his ear with a plug. Read how the human/machine interface meet more and more. "The line that has long separated human beings from the machines that assist them is blurring as complex technologies become a visible part of people who depend upon them. Unlike pacemakers and fabricated heart valves that are embedded in the body, these technologies are, so to speak, worn on their users' sleeves.
Increasingly, amputees, especially young men like Mr. Clapp, and soldiers who have lost limbs in Afghanistan and Iraq, are choosing not to hide their prosthetics under clothing as previous generations did. Instead, some of the estimated 1.2 million amputees in the United States proudly polish and decorate their electronic limbs for all to see.
Long an eerie theme in popular science fiction, the integration of humans with machines has often been presented as a harbinger of a soulless future, populated with flesh-and-metal cyborgs, RoboCops and Terminators. But major universities like Carnegie Mellon and the University of California at Berkeley, as well as companies and the United States military, are exploring ways in which people can be enhanced by strapping themselves into wearable robotics, or exoskeletons.
'There is a kind of cyborg consciousness, a fluidity at the boundaries of what is flesh and what is machine, that has happened behind our backs,' said Sherry Turkle, the director of the Initiative on Technology and Self at the Massachusetts Institute of Technology, who is writing a book on robots and culture. 'The notion that your leg is a machine part and it is exposed, that it is an enhancement, is becoming comfortable in the sense that it can be made a part of you.'
Maybe they can enhance penises with prosthetics, so that all the penis enlarging spam I get can actually start offering something real. God knows what anyone would do with a 12" dick, but there are some men out there who think they need one.
