Introduction Any idiot can write code. Even teenagers can sling gates and PAL equations around. What is it that separates us from these amateurs? Do years of college necessarily make us professionals, or is there some other factor that clearly delineates engineers from hackers? With the phrase "sanitation engineer" now rooted in our lexicon, is the real meaning behind the word engineer cheapened? Other professions don't suffer from such casual word abuse. Doctors and lawyers have strong organizations that, for better or worse, have changed the law of the land to keep the amateurs out.

Engineers were viewed as the celebrities of the age, as the architects of tomorrow, the great hope for civilization.

Our successes at transforming the world brought stink and smog, fac- tories weeping poisons, and landfills overflowing with products made obsolete in the course of months. The Challenger explosion destroyed many people's faith in complex technology (which shows just how little understanding Americans have of complexity). An odd resurgence of the worship of the primitive is directly at odds with the profession we em- brace. Declining test scores and an urge to make a lot of money now means that U.S. engineering enrollments have declined 25% in the decade from ……
