How is this an example of him being right? He neither proved that his idea worked, nor did he prove that maglev didn't work. Obviously he has gotten some things right, which is a good thing. But Musk has an extraordinary track record of being wrong about a lot of things. That, by itself, is not a problem - you lose, you learn, you fix, you win. The problem is that Musk aggressively attacks public policy with his aggressive wrongness: - Don't invest in surface public transit, we're so close to full self-driving cars and then traffic will be solved! - Don't invest in subway systems, we're gonna build better tunnels for self driving cars! - Don't invest in high speed rail, we could build a hyperloop for much lower cost and it would be 3x faster! - Don't dive in there to save those kids dying in the flooded tunnel, that's dangerous! Trust me, I'm gonna build a submarine that can get them out! As far as I'm concerned, Musk can be wrong all he wants, but stop fucking with the world's decisions if you're gonna insist on being wrong all the time.
