One machine can do the work of fifty ordinary men.  No machine can do the work of one extraordinary man.  ~Elbert Hubbard, The Roycroft Dictionary and Book of Epigrams, 1923

 
All of the biggest technological inventions created by man - the airplane, the automobile, the computer - says little about his intelligence, but speaks volumes about his laziness.  ~Mark Kennedy
 

We've arranged a civilization in which most crucial elements profoundly depend on science and technology.  We have also arranged things so that almost no one understands science and technology.  This is a prescription for disaster.  We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.  ~Carl Sagan
