Almost everything mentioned in this article works when professional and educated people are operating them. If you start reducing to the lowest common denominator most people are not capable of walking across the room successfully.

A fact of life that EVERYTHING breaks, even LEDs burn out ... sometimes in a matter of minutes???
This is why you have techs and administrators. To make certain that when (not if) things break, normal operation can be restored efficiently.
