Not sure what future he is referring to, but if he means mach-5 private drones (i.e., one or two passenger) then it is not the future I want to live in. We need to advance public transport for the masses and the use of renewable energy for it. We don't need hyper polluting single-digit passenger private transport for the ultra rich.
If, as suggested below, it is all a cover for developing hypersonic autonomous killer drones, count me out too.
