We are in the dawn of the post-car era in terms of urban planning. With the arrival of fully-electric transportation, we can finally move transit systems under the surface and organize cities around people, not cars. Advancements in speed rail technology (including Hyperloop), city-level climate control, and land reclamation technologies allow for urban expansion in previously undesirable locations. And, on the investment side, the world has trillions of dollars of long-term capital seeking alternatives to the stock market and bonds. Privately built and operated cities can emerge as a new asset class for capital markets.
