Lewis Mumford (PDF):
The inventors of nuclear bombs, space rockets, and computers are the pyramid builders of our own age: psychologically inflated by a similar myth of unqualified power, boasting through their science of their increasing omnipotence, if not omniscience, moved by obsessions and compulsions no less irrational than those of earlier absolute systems: particularly the notion that the system itself must be expanded, at whatever eventual cost to life
From a speech given on January 21, 1963. The relevance of Mumford's remarks seems to have only grown in the intervening sixty-odd years. Easily one of the best essays I've read in the past year.
