This is a very strange conclusion. I love my remote office for 'deep work' but most of the connections (breadth?) I make on some topics are with chance discussions with peers, colleagues, managers, directors. The recent slice of forced remote has let me go deeper on some topics but also miss ways in which my work may have been easier or more impactful. I'm thinking of 'hey I think we might need something similar to what you're doing', 'hey I think we did that in the past and it went so wrong, look up such and such', or even 'this subject is politically doomed, tread carefully'. Those kinds of conversations are almost impossible to 'chance upon' over chatrooms...
Maybe our culture is bad, too oral, and maybe some people in other corps manage it fine and I'm missing something...
