I don't think the points made in that video will survive long-term. Zoning laws will be forced to change, i.e. minimum parking laws, single zone areas, expensive high-end designs, high-pressure plumbing per residence, lack of use of fiberoptics for sunlight lamps etc. Ideal designs will need to change to accommodate all the empty space that will slowly fall apart without use. I would hate to see all these huge buildings demolished on a shortened lifecycle.
