I think a lot of the skills you learn around how you interact with people in a professional setting, developing a sense of when to ask someone for help vs. work through a problem yourself, and how to develop software professionally. I've found that we have a lot more work taken down a wrong path because it's not as easy to check in on someone remotely without it coming across as micromanagement of more junior developers. I appreciate that a fair portion of that "blame" lays with the more senior members, but I've at least found that some things that would easily be resolved face to face, or with the kind of coffee break chat you get in person, have festered on longer than they necessarily should have.
all great points! this is why I'm not the hugest fan of "remote-optional" workplaces. remote-native companies tend to develop methods to achieve what you've mentioned without being in an office. remote-optional.. not as much.
