A little story:
An editorial in a California regional newspaper reported a story about a man in California who built an ingenious machine in his garage. Everything high tech imagined he had acquired over the years was used to make this huge contraption perform complex operations.
So from the control panel, the operator watched with satisfaction as the lights blinked and dials turned as an indication that all was in proper working order. Technicians from all over rated the contraption a marvel of technology. However, there was just one minor flaw. The machine was not designed to do anything! It was developed by an absentminded gadgeteer who just got carried away with the wonders of the new machine age.
