Telephones

Quick article about how the US senate almost banned rotary phones - https://www.senate.gov/artandhistory/history/minute/Senate_Considers_Banning_Dial_Phones.htm

An old boss of mine had an amusing anecdote about somebody years ago saying that with the enormous growth of telephones in the US everybody would be employed as a telephone operator.  The amusing part of my boss' anecdote was that this person was actually right.  Since we type in phone numbers when we want to talk to somebody, we are in effect working as a phone operator.

Of course in good old 2019, we pretty much have contact apps universally available so we aren't likely to have to type in phone numbers any more.  Unless it's from the menu of the new restaurant that opened and we want to get takeout.
