Did you invent graphical user interface?

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.
