My dream is that this gets built in a different setting: offices. Imagine self-driving desks in a giant flat warehouse without a single wall. You could pick a travel program where your desk would slowly roll around the perimeter, or just hang out in the middle. You could program it to maximize distance from any other desk if you wanted privacy. And of course the desks would be networked and their position could be overriden by a master controller that had access to the company calendar, so when it's time for the mandatory standup meeting your team's desks would automatically get together in a single spot.
