I'm a programmer on a team with other programmers, many of us remote.
We're not standing around a water-cooler talking. We're on team chats. We're reply-all'ing to email-chains. We're sharing memes. Half the time we talk across chat when we're sitting in the same room.
These aren't formal design docs or code output [the analogy to flight controls], this is our water-cooler talk, and it can all be subpoenaed in a variety of situations, to be read into court record and taken out of context for the rest of time.
