Sunday Book-Thought 34

All tools are externalizations of originally integral functions. But in developing each tool man also extends the limits of its usefulness, since he can make bigger cups hold liquids too hot or chemically destructive for his hands. Tools do not introduce new principles but they greatly extend the range of conditions under which the discovered control principle may be effectively employed by man. There is nothing new in world technology’s growth. It is only the vast increase of its effective ranges that are startling man. The computer is an imitation human brain. There is nothing new about it, but its capacity, speed of operation, and tirelessness, as well as its ability to operate under environmental conditions intolerable to the human anatomy, make it far more effective in performing special tasks than is the skull and tissue encased human brain, minus the computer.
R. Buckminster Fuller
