They don't? Microwave ovens that cook precisely, Dyson vacuums that speed up cleanup, alarm clocks that make coffee, answering machines to keep interruptions down and thwart telemarketers, sensor-equipped clothes dryers get exactly the moisture out that you want, Tivos that make sure you watch the (commercial-less!) shows when you have a minute, GPS navigation to the next play date, iPods that make sure your dose of Doug on the radio is loaded for your commute tomorrow ...
Sure, I still want a jet pack; but robots are here, baby. And they are busy.
