This. I think of this every time I hear the "spontaneous connection" argument. Decades ago, this was true, but it hasn't been true anywhere I've worked for at least 15 years.

Now, even when people are all in the office, very nearly 100% of the communications are done via chat programs (even to the person next to you) or email. For good reason, really. It minimizes the risk of interrupting someone deep in the flow.
