Also, don't forget that there's a lot people naturally discuss in those side-conversations that they really don't want to have "on the record" or "discoverable" in the legal sense. The moment someone tells you that lawyers might scrutinize everything you discuss, you become far more hesitant to have open conversations.
Of course that's why many business types quickly transition from Email to "call me", but that's less likely to happen with tech types and more casual topics.
You just made me envision a robot warehouse where humans drive the forklifts remotely to move items around.
this is a very very good point! but I don't think that being remote or not make this communication problem worse or not.
A lot of people like it, learn from it, and also provide me with advice when they happen to know something I do not.
There's also a case where some jobs need to be done in-person. A good example is a restocker for a grocery store. You can't move boxes remotely. Similarly a surgeon can't do a surgery remotely.
