Technological advances in our automobiles have spoiled us. Early on there were just four gauges: gas, water temperature, oil pressure, and battery discharge. These four indicators were like a whole set of encyclopedias about the state of your ride back in the day. Compared to operating information available now, however, just having those four gauges seems laughable. For perspective, though, the all-important “check engine” light did not become standard until 1996. In just over 25 years, automobile diagnostics have progressed from “check engine” to screen after screen of operating analytics. Technology is like that across the board. One seminal breakthrough can expand capability exponentially. It’s too bad there is no “check engine” light for computers.
