The problem with only hiring "idea guys," techbros and consultants is that eventually you'll need actual work done.My original video on the Hyperloop: https:...
The actual speed that matters should be calculated including any on- and off-boarding, so planes aren’t all that fast for short distances (considering most people probably need at least an hour before flight in the airport and at least like 20 minutes after arrival).

Maglev, they hold the current rail speed record with 603 km/h: https://en.m.wikipedia.org/wiki/Railway_speed_record
By comparison the cruising speed of a current airliner is ~900 km/h
Maglev is expensive both to build (because you need magnetized rails) and to operate (uses more energy overall than a shinkansen).
There is a reason why Japan built a prototype decades ago but never built a commercial line.

At least 20 minutes is not enough to get to a place you want to visit though, while trains in many places ride straight into the city.
Some more modern cities air ports near the centers as well
