Kevin Warwick is so serious about his technology he had a silicon chip surgically implanted in his left arm in 1998. It allows the Reading University cybernetics professor to automatically open doors and switch on lights in his office building. He believes the future wil bring messaging between human and machine brains. You can hear his views on robotics in a lecture titled "Will it be super intelligent machines or cyborgs?" at the BETT educational technology show at Olympia, London, next Wednesday in seminar room D1 at 11am.
