In person interactions is better, but we have a good amount of open-source projects that do fine with remote interactions. The issue with remote interactions is with processes. Instead of having tooling to promote adhoc interactions, most teams will get into some kind of rigid structures because the tooling is imposed from high.

I loathe having slack because it quickly becomes full of noise. There should be friction from having another department chiming in. Having announcements in #general and #random have a cognitive load. I like email, because you can have filters and deal with things when it's suitable to do so. Slack is no where close to that.
