Famous quotes containing the word electronic:
“The car as we know it is on the way out. To a large extent, I deplore its passing, for as a basically old- fashioned machine, it enshrines a basically old-fashioned idea: freedom. In terms of pollution, noise and human life, the price of that freedom may be high, but perhaps the car, by the very muddle and confusion it causes, may be holding back the remorseless spread of the regimented, electronic society.”
—J.G. (James Graham)
