> most workers were probably head-down looking at paper on their physical desktop
Not really. If you go back to the 50's you will find armies of people looking down at paper, reading and writing, but not most. By the 80's all of those people had machines on their desks, while most didn't do paper work.
I believe the majority of people only started doing information (since the paper isn't there anymore) work this century on the rich countries. On many countries they didn't yet.

What kind of machines? Computers? My father was an office worker his whole life. He didn't get a PC on his desk until the 90s. Before, he had a type writer.

Also, sales people were always loud.
