"It's a miracle!"
Remember the great breakthrough of “Carbonless Carbon Paper” which used microcapsules of ink on the paper? Man, was that ever cutting-edge technology! I wondered at the time “what will they think of next.”
All of my early field engineering correspondence when I was overseas was via Telex. That was hot stuff. In the US it was via phone (with my very own AT&T Calling Card, pre Bell-breakup) and hand-written field reports delivered via snail mail. It was indeed nice being totally disconnected and unreachable outside business hours.
