Do we really need to move at such speed?

Two great machines in store: The Spike S-512 and the Hyperloop:
1) The Spike S-512 is a projected supersonic business jet, designed by Spike Aerospace, an American aerospace manufacturer firm based in Boston, Massachusetts. If produced, it would allow long flights for business and private travelers, such as from New York City to London, to take only three to four hours instead of six to seven. The company planned to promote the project with an exhibit at the 2014 EAA AirVenture Oshkosh airshow. The aircraft will not have windows for the passengers, instead it will be lined with tiny cameras sending footage to thin, curved displays lining the interior walls of the fuselage and Spike originally expected to launch the plane by December 2018. Spike Aerospace expects to fly a subsonic scale prototype in summer 2017 to demonstrate low-speed aerodynamic flight characteristics, followed with a series of larger prototypes and a supersonic demonstrator by the end of 2018 and expects to certify the S-512 by 2023. (Wikipedia)

2) The hyperloop is a proposed mode of passenger and/or freight transportation, first named as such in an open-source vactrain design released by a joint team from Tesla and SpaceX. Drawing heavily from Robert Goddard's vactrain, a hyperloop comprises a sealed tube or system of tubes through which a pod may travel free of air resistance or friction conveying people or objects at optimal speed and acceleration. Elon Musk's version of the concept, first publicly mentioned in 2012, incorporates reduced-pressure tubes in which pressurized capsules ride on air bearings driven by linear induction motors and air compressors. (Wikipedia)
