An electric guitar is a fancy lute. A diesel backhoe is a hydraulic lever. Computers are electronic abacuses, typewriters, notepads, slide projectors, clocks, record players, filing cabinets, or whatever you like at the time. My point is we have always been using instruments to extend our reach, strength, flexibility, and productivity. Basket, knife, digging stick, bow and arrow, animal trap, and all the rest are levers of our cultures, screwing, multiplying, and dividing.
