So, AOC is not crazy or stupid - sorry peeps. Maybe naive, but a lot of the stuff in her Green New Deal are things planners are already looking at. I agree that most politicians would never offer these radical ideas, but they are not off the wall.
It has long been known that a system of UHS (Ultra High Speed) trains would be more efficient than air travel. Also, the footprint of train tracks and stations are much less destructive than airports. Many countries use elevated tracks to allow farming and livestock to pass under train lines and to avoid automobile intersections. We are way behind on this, Japan, France and others already have trains doing 200+ mph. Even UHS trains are super efficient and with battery tech, they could be nearly carbon neutral in just a few years.
Advanced self driving cars have long been discussed as a preferred option to building more and more roads. These cars could run the interstates in virtual trains at 100 mph, dropping off cars at their exits.
Essentially a NASCAR draft every morning to work! No more traffic jams due to centrally coordinated traffic flows. We are pretty close to being able to do this technically now, problem is too many human piloted cars mixed in that will gum up things and cause massive pile ups.
I was at a seminar (2 years ago now) where the key note speaker said in 5 years computers will be as smart as a high average human. In 10 years they will be smarter than any human ever can be. What leaders aren't telling you is that our economy won't need people very soon. Computers won't just replace blue collar jobs, they will soon start replacing white collar jobs. So we are going to have to do something radical and redefine what "work" is. One solution is a standard income minimum. This will allow society a little more time to adjust, but just a little IMHO. A standard income minimum is not a giveaway to lazy and brown people, it is a pacifier to keep people displaced from all work by machines from becoming violent. BTW: brown people aren't taking your jobs, your iPad is. The other is using military force on the population.
We are at a moment where something radical is the only passable solution. Politically correct steps are not going to address the future that is inevitable. AOC's proposal is certainly a long shot, but you can believe that the grumpy old white men's solution isn't going to benefit you unless you have a billion in the bank. We're at the point where something disruptive has to happen.
