In my experience most people are really bad at jumping out of their team and silo remotely, especially software developers. Some people might make it work, but that’s not my experience with the majority of coders. Also as good as zoom/teams/slack is, it really doesn’t compare to an in person conversation. It’s a more formal and often friction filled experience. Conversations remotely are mostly done with purpose, you call someone for a reason. This makes relationships really transactional. The in person aspect drives a lot more potential for organic conversation. Remotely I might see two of my colleagues in a huddle on slack, if I happen to be looking at their profiles at the right time, but I would never join them. Conversely however I’ve commented and jumped in on conversations between the ML engineers sitting behind me all the time, and vice versa when I’m discussing python programming.
