"Ken Thompson has an automobile which he helped design. Unlike most
automobiles, it has neither speedometer, nor gas gauge, nor any of the
other numerous idiot lights which plague the modern driver. Rather, if the
driver makes a mistake, a giant “?” lights up in the center of the
dashboard. “The experienced driver,” says Thompson, “will usually know
what’s wrong.”"
