Yeah, it feels necessary and a weird mix of inevitable and impossible. It meets so many of our needs, it gives us a practical every day reason to invest in technology and manufacturing of something we can sell to the world and ourselves, it gives us something to focus our energies on and we can power it with solar these days. And politically It's a non starter. I don't know how long the country can remain in one piece. There's a massive anti infrastructure propaganda system. It would be brutally opposed by the air travel industry. If a democrat starts it a republican will end it before ground breaks. And people are pissed about the California high speed rail's delays and issues and lack trust in rail.
It requires massive changes in our country's politics, but any stable position focused on the common good will ultimately come to the conclusion to do it.
