I don't know. Since I see "hyperloop" as more akin to a pipe-dream, dangling this "cool" idea in front of people is destructive if a) it never gets done (probably because it's not cost-feasible, not from alack of imagination on the part of the public) and thus b) money to fund systems that actually do work and need funding (Amtrak) get short shrift.
I disagree. We're very short on dreams these days. And I also don't think "pipe dreams" will siphon money away from work that needs to be done - it's the general lack of will to do anything other than very incremental fixes that currently eats that money.
