Suppose that in 1945 a respected sage had been asked, "What do you see for the future?" and he had replied, "Rust, sand and soot." He would have been considered a pessimist. An optimistic sage might have replied instead: "The future will be powered entirely by atomic energy. Contagious disease will be eliminated by antibiotics such as penicillin. Harmful insects will be eradicated by DDT and similar chlorinated hydrocarbon insecticides."
