Well the tube-based transportation system has come a long way and to prove just how far here's a sneak peak at what travelling in one of the trains will be like.
Hyperloop Transportation Technologies (one of the companies that has taken on Musk's concept) released a short video during a conference call that showed how they would make travelling in a tiny capsule not only bearable, but actually pleasant.
The company has partnered with Re'Flekt, a firm in Germany, who will be creating the next-generation of screens for the Hyperloop's windows.
You see because Hyperloop works by sending a capsule down a frictionless vacuum tube there's no chance of getting a nice view.
To compensate the company has designed a concept which creates a fake window which would show what the passenger would see if they did actually have a window.
In addition the windows would act as information centres, providing up-to-date info on the weather as well as upcoming events at their destination.
HTT has got a partnership in place with the Slovakian government and the hope is that they can create the first looped system between Bratislava and Budapest.
