>Of that particular list, I would say levitating trains are currently solved from a technical view point[0], and are awaiting economic viability. No, they're not. They're already economically viable: that's why Japan is building one between Tokyo and Nagoya right now, and it'll be in service later this decade. The current bullet trains are huge money-makers and have been for a long time; the Chuo shinkansen will be too.

China's Maglev keeps losing money. Something is built and in service == economically viable in decision-makers(often politicians!)' minds != economically viable.

  China's "maglev" is a short train to the airport. It's for demonstration purposes only. Japan's maglev is connecting the largest city in the world with one of its other largest cities. When complete, it'll connect the 3 largest metro areas in the country together. Japan already has a bullet train that does exactly this, and it makes tons of money, and it's been doing so since the 1960s.

    Japan's commercial maglev is not yet completed. All current Japanese high speed services are conventional rail. There is a small test track for maglev and an under-construction commercial maglev with no public completion date (https://en.wikipedia.org/wiki/Ch%C5%AB%C5%8D_Shinkansen https://en.wikipedia.org/wiki/Ch%C5%AB%C5%8D_Shinkansen).

      >with no public completion date Wrong, the first leg will be complete in 2027. It takes some time because 90% of it is underground. Yes, it's not completed yet, but it doesn't matter: it's virtually guaranteed to be profitable, just because the current shinkansen are.

Japan doesn't subsidize their maglev trains at all?

The point being, RTSC just tears the floor out on some of the operating costs for it, so since all the control schemes and even a lot of the design work is already established practice, maglev /ought/ to proliferate a lot more quickly than, say, municipal scale fusion reactors.
