Quotations

Education makes machines which act like men and produces men who act like machines.

It is questionable if all the mechanical inventions yet made have lightened the day's toil of any human being.

The real problem is not whether machines think but whether men do.

B.F. Skinner, Contingencies of Reinforcement, 1969

We are becoming the servants in thought, as in action, of the machine we have created to serve us.

You cannot endow even the best machine with initiative; the jolliest steam-roller will not plant flowers.

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.
