While plans developed by Elon Musk for the Hyperloop are certainly not very good, the actual hyperloop will be part of future cities. Places like Virgin have already developed incredible working models. Thus, we will likely see this and other high-speed rail projects in the coming years. High-speed rail or bullet trains have already been in use in places like Japan for years now. The hyperloop will likely be another step in this direction. Only, the hyperloop will be built underground and supposedly move at hundreds of miles per hour. Thereby cutting travel time down to destinations by an extreme amount. Planes may no longer be required to go from state to state here in the U.S. or nation to nation in places like Europe and Asia. A hyperloop could be employed instead, and potentially be much cheaper too.
