Investors are not stupid or blind. Hyperloop is similar to the Maglev train technology developed in Germany and Japan for the last decades. The inventor of the maglev train even thought about hyperloop. But so far just one single commercial maglev train route has been build. And the suck costs are extremely high. The six billion Musk estimated are wrong, it won't be six billion, it will much, much more than that. Investors don't invest in hyperloops not because of the 9 theories the author is mentioning but because hyperloop are not an alternative to conventional trains.
