| But, mechanical machinery has been around for a 
| long time, almost everyone can operate complex 
| machinery (a car for example), yet only a few 
| people ever learn (or care) what goes on inside; 
| fewer ever actually repair or enhance the machine. 
| Almost nobody designs cars from scratch; unless you 
| work in the automotive industry, I doubt you've ever 
| met someone who can design a cam shaft, a piston, 
| or an automatic transmission. Yet professional 
| programmers do the equivalent every day.

No, we don't.
