My close friends and family know that I often tend to redirect static conversations toward one of my favourite topics: the pending advent of the Hyperloop! It's like real-life Jetsons!
In case you aren't familiar with it, I highly recommend you read up on it because it has the potential to change the entire world as we know it - https://en.wikipedia.org/wiki/Hyperloop
In short, it is a system of travel through near-complete vacuum tubes and allows for human commuter travel at speeds unparalleled by today's offerings. Think "i can live in New York and get to LA in 2 hours for work" kind of fast. Incredible.
The entire travel industry as we know it would be flipped on its head. The implications are crazy.
Who's the genius behind it? Well Elon Musk of course.
Here is some news from today - http://uk.businessinsider.com/elon-musk-hyperloop-new-york-washington-dc-2017-7?r=US&IR=T
They've been given the green light to build one from Washington DC to NYC. Meanwhile on the westcoast they've been talking about building one between LA and San Fran.
