Hyperloop is premised on a sharp reduction in the cost of creating tunnels (~order of magnitude+). I believe that premise will be valid within 10-15 years. Hyperloop probably won't work unless and until it is.

Existing High Speed Rail is already a superior form of transport for short distances (600 miles or less). By "superior" I mean safer, more convenient, and comparable in duration. Hyperloop would be as safe/convenient as HSR, and much faster. For longer distances, air travel would remain superior (faster).
Because hyperloop targets sub 600 mile distances, a global network of interconnected nodes is unnecessary and irrelevant. Others have proposed tubular systems for longer distances at much higher speeds with (sub-sea) intercontinental connections, but that seems much more difficult, even if it's physically possible (vacuums, etc).
A new technology could supplant all of the above (eg. rapidly re-usable rockets, teleportation, or something else), but that's out of left field.
