The German Transrapid gave very little advantage over regular trains and was bound to fail from the beginning. https://en.wikipedia.org/wiki/Transrapid

The Hyperloop has the same problems (technology still developing, requires new, incompatible infrastructure) but it has one big advantage:

In contrast to the Transrapid, it can compete with planes regarding to speed.

What both technologies share: They require electricity, which is good. Electricity can be generated easily, possibly with thorium reactors in the future. It is hard (but possible, e.g. reduction of CO2 to methanol) to create combustible fuels for plane engines from electricity. Electric transport will likely overtake all kind of combustion engines.
