Bill Gates makes a speech. "If the automobile industry had developed
like the software industry, we would all be driving $25 cars that get
1,000 miles to the gallon." To which an automobile executive retorts,
"Yeah, and if cars were like software, they would crash twice a day for
no reason, and when you called for service, they'd tell you to
reinstall the engine."
