Not so friendly reminder that musk specifically came up with, and pushed, for hyperloop knowing that it would never be made, as an effort to stop the development of highspeed rail in America and shift all political discussions of it because "something better is around the corner":
As I’ve written in my book, Musk admitted to his biographer Ashlee Vance that Hyperloop was all about trying to get legislators to cancel plans for high-speed rail in California—even though he had no plans to build it. Several years ago, Musk said that public transit was “a pain in the ass” where you were surrounded by strangers, including possible serial killers, to justify his opposition.
Also: 2024 update, the total length of China's high-speed rail tracks has now reached well over 45,000 km, or 28,000 miles, by the end of 2023.
They are additionally five years ahead of schedule and expect to double the total number within ten years. And, before someone inevitably complains about "how expensive it is", they are turning over a net-profit of over $600M USD a year.
In particular, the big push in Wisconsin for expanding Amtrak (not even high speed rail) circa 2010 was killed by Republicans taking office. The trains themselves were already paid for, but they never took delivery. So the state paid all the costs for nothing, and IIRC, it was actually more expensive to cancel it at that stage.
I recently took the Amtrak from Columbus, WI to Minneapolis. Even as limited and poorly implemented as Amtrak is compared to European rail, it was still a more pleasant experience than either flying or driving. I always feel exhausted after a flight; even though you're not physically doing much, the whole process is so unpleasant that I need to collapse in bed afterwords. Didn't feel that way at all on Amtrak.
