Every tool is an extension of the human mind. Play an instrument, drive a car, swing a bat... Sure you're using your fingers, legs, and arms, but once your mind adapts, you're thinking and reacting more directly about the new inputs and outputs the tool gives you. There are some neurological studies on musicians and their brain maps that demonstrate this. Think of other types of tools like hearing aids and artificial limbs. Over time, the brain adapts to use them much like the real thing. Some tools are just "upgrades" far removed from what the human body is naturally capable of. The tools we use definitely shape the way we think. Marshall McLuhan: "We shape our tools, and thereafter our tools shape us."
