Strictly my opinion: upper management who are not servant leaders and individual contributors of their own account are, in fact, doomed. No amount of Kafka-esque office theater will save them from cuts.

As for support businesses (food / clothing / commercial real estate / parking / technical services), nearly all of that is also doomed. Urban planners had best figure out how to address the issues of keeping more valuable services (commercial kitchens, entertainment, boutique retail) from fleeing to places closer to home.
