Planet wide high speed rail doesn't make much sense, it is better of medium sized trips. Flights are will always be better for intercontinental trips. Vacuum trains could be faster but would be so expensive to build. Issues would be big deal in evacuated tunnels.

CA HSR is slow partly because the state government has limited funds and giving out slowly. The federal government should have been contributing more. The other problem is it kept getting delayed from legal issues, mainly from acquiring land. Going forward is bad because they decided to do the easy part first and leave the hard tunnels for later.

Vacuum trains are what high altitude airliners are.

There should be a high speed rail for every minor leg along the way. Efficiency is relative. People should be able to ship their car by this system instead of renting if they chose. Or use it to go sight seeing in any direction along it's web. The whole point is freedom to move around.

The cost of the HSR is tiny and inconsequential. For the 40 million residents of California it amounts to about $20 a month over the 10 years the fund has been going. It hasn't even spent 50% of the total fund yet. If construction was even 2x the current rate we would already have the central valley done. So I know they are slow rolling it. That's my point. They can speed things up even just a little.
