This has long been true to some degree when you work with people scattered around the world. But it's a legit concern that, overall, we're probably developing much shallower relationships with the people we work with compared to when we were together in-person more of the time. Doubtless there are people who prefer just tuning out co-workers as much as possible. But it's reasonable to ask how it will affect many companies in the longer run when many co-worker relationships are very surface compared to pre-COVID.
