A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship,
design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take
orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure,
program a computer, cook a tasty meal, fight efficiently, and die gallantly. Specialization is for
insects.
Robert Heinlein
