> and if someone is willing to talk in person they’re almost certainly willing to talk over video chat too.

Strongly disagree. The culture is different. I didn't always love other people popping by, but they could just do it in a way that isn't really done with voice chat where I work. It was probably better for the team that they did. I definitely found myself doing this too.

Unless you work somewhere with a policy to avoid stopping by someone's desk at all costs, unless you were sure the other person wanted it (in advance), it's not like voice calls at all. If I just call someone, I'm being pushy. I have to ask first, and even then I feel like I'm inconveniencing them. I'm certainly not going to just call people out of the blue, even ones I'm friendly with just to chit chat. In the office, we'd "run into each other", though.
