True, but it doesn't change the fact that in 2025 an engineer with a closed door but ethernet and cell connectivity is still likely to be inundated with a continuous stream of notifications and other forms of electronic correspondence with his peers.
put another way, I'm getting exposed to hundreds of ideas and people -- and probably 40% bots -- just being on HN
a researcher in 1971 could maybe get yesterday's news via newspaper, or maybe radio -- but if they're closed door they're focusing, so they hear nothing else.
