Quinn and Micky are on the vidphone live with an engineer on Earth.  Today they sit down with Douglas Lee, a civil engineer focused on harmonizing human structures with the planet and healthy living.  He specializes in the production of modern public transit systems.  What will be the fate of urban centers in the wake of the recent pandemic?  Mr. Lee shines light on the possible restructuring of cities as robotic distribution hubs, a move to delocalized, hyper-local fabrication, and the resurgence of personalized agriculture.
