I want to communicate with people in person. If I'm going to pair with someone, I want that to be at their desk. If I'm going to brainstorm with somebody or go over some complex math, I want to do that at a real physical whiteboard. I have yet to meet anybody who communicates better over slack or zoom than they do in person. So either I want you to be in the office for the greater communication bandwidth, or you want me to waste time trying to exchange ideas over sub-optimal channels. Either way, we're at an impasse.
