Speaking of vacuum cleaners, I gather more than a million Roomba devices are now droning around the carpets of America, sucking up the dust entirely on their own and taking several times as long to do it as any incompetent human.
Meanwhile, the Koreans are trying to develop a robot guard which can detect movement and shoot on sight. Charming. At present all these machines require a human somewhere along the way to plug them in and tell them what to do. But the experts say that it is only a matter of time before robots can think for themselves.
