Datapoint: long ago (decades) I worked for a large well known valley software company, for several years. During that time I worked with many colleagues who were somewhere on the same campus, but I never physically met them. Obviously I was around my team mates, manager, and I attended many cross-group in-person physical meetings, but the number of people I interacted with online only was large. This was before video conferencing existed, just email phone and IM.
