"Connectedness" is a qualitative answer that's subject to change from person-to-person. I work best when connected with my peers over Slack or something similar, so I can streamline my workflow away from arranging meetings or interrupting others. Obviously everyone's job is going to look different, but that also explains why management is so frustrated with remote work while many devs don't care one way or the other.

However you slice it, remote-vs-office is a matter of perspective. Trying to make one uniform office/remote policy is not working.
