Hopefully skyscrapers will build more inter-building bridges in the future. I wonder if the confluence of telecommuting, robotic goods delivery, and the penchant for urban living might mitigate the skyscrapers&#x27; elevator-to-floor optimization challenge by shifting the utilization pattern to one that sees more inter-floor and inter-building travel instead of ground-to-floor travel. There has to be some fascinating data collected by the elevator companies on the statistics of elevator service (mass, destinations, <i>etc.</i>).
