You (Yes, YOU) cannot afford to ride the Hyperloop

The article describes pretty much exactly how Concorde worked - it was faster, more convenient, but exclusive and expensive. You even sacrificed a lot of comfort for your trouble - I never got the chance to fly Concorde, but have toured one, and can't deny you get about as much space per seat as you do flying cattle-class in a modern airliner. So there's definitely a historical model here.

The joke, of course, is that Musk's early remarks about the Hyperloop involved drilling one between his home and Tesla's office to avoid Californian traffic. This is very likely to bear out in principle - it's a rich person's toy that benefits nobody else. But such are the perils when influential people have far more money than sense to do something useful with it.

Que sera.
