Or perhaps the microprocessor?

Probably not.

Still, you might occasionally be tempted to make fun of outmoded technology. Resist that impulse, if you can.

Unless you are a visionary engineer or gifted industrial designer, you probably couldn't have come up with the idea for devices now considered obsolete.

But perhaps I should just speak for myself. So I will.

I could not build a linotype machine to save my life.
