In defense of machines, by George Boas:
We are first told that though man invented [machines] to be his servants he has become theirs. ... This argument is a gross exaggeration. Man is no more a slave of his machines than he has ever been, or than he is to his body ...
We must each establish a system of values for ourselves or absorb that of our social group, and judge machines by it as we do everything else. There is no other way of evaluating anything.
