Motherboard TV (Vice) has a video interview up with Kevin Warwick, a Professor of Cybernetics at Reading University, who in 1998 became "the world's first cyborg." We've blogged about him before here on Boing Boing. Warwick had a radio frequency ID implanted in his arm.
As a result, he can turn on lights by snapping his fingers; once he let his wife's brain waves take control of his body (she's also cybernetic). This isn't just for fun: Warwick is certain that without upgrading, humans will someday fall behind the advances of the robots they're building - or worse. "Someday we'll switch on that machine, and we won't be able to switch it off."[ via BB Submitterator ]
