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, 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, Time Enough for Love
