"C. Montgomery Burns: [over P.A. system] Mindless drones! Return to your ugly families!
Homer Simpson: D'oh! "

This Simpsons quote depicts Burns workers as robots without feelings. This metaphor brings out the qualities humans have for getting obsessed with their job or for getting caught up thinking that the job is their life. They do the same thing day in and day out without reprieve. I think everyone at some point has felt these mind numbing effects of monotony. We start to question if all this work could be done as efficiently as a robot.

"I want to PUMP you up!"
Arnold Schwarzenegger

This quote is taken from Arnold's workout videos. He depicts the human body as a ball or Nike shoe that can be expanded with air or some other kind of substance. The obvious metaphorical meaning is that he wants to get you exited about working out or that he really does want to make your muscles get bigger. But he didn’t say that he said this metaphor and it turned into a catch phrase, a great advertising trick. Its interesting to watch Arnold's tapes because throughout the whole session his words of encouragement are almost all about the body being a machine carefully crafted and controlled by the mechanic, you.

"If it keeps up, man will atrophy all his limbs but the push-button finger.”
~Frank Lloyd Wright

This may not be a direct metaphor to humans as a technology but the finger certainly is considered part of a machine when using the adjective push-button to describe human's drive for making life simpler by advancing technology. Wright warns us here that man might get too lazy and eventually have no need for anything else but a finger to push all the buttons to take care of life for us. But what kind of life would that entail? Not a pleasant one for sure. I see a future of quadriplegic people and millions of robots and machines living life for us. Bleak indeed.
