Currently I'd say probably Musk because he's taken my money too(right now he's much more a liar than a scammer).
Took money for what, if any?
Musk like Holmes took millions of dollars from investors. Holmes knew she had a machine that didn't work. Musk who knows the science has to know Hyperloop would never work, yet accepted money from investors.
Musk does not own nor operate nor have any vested interest in any Hyperloop company!
I actually do not rule out that the whole thing on his part is a gigantic troll.
What about his own Hyperloop compnay?
If I provide you with some "credible" information which contradicts your statement could I change your mind?
Elon Musk is building his own HyperloopThe billionaire will go into competition with the startups he inspired with his white paper.
Elon Musk may have dreamt up the Hyperloop, but the bulk of its development has been carried out by others. When he unveiled the white paper in 2013, the South African billionaire said that his vision was "open sourced," and it would be for other startups to build it out. Now, however, sources close to Musk say that he will now build his own Hyperloop, starting with the New York to Washington D.C. route.
The news was confirmed in a statement sent to Bloomberg via Musk's Boring Company, which said that it wants to "accelerate the development of this technology as fast as possible." That may pose an existential threat to the number of startups that have begun working on their Hyperloop designs. Businesses such as Hyperloop One, Hyperloop Transportation Technologies, Arrivo and TransPod have new competition.
Musk tweeted that he had received informal approval to build his first Hyperloop, from NYC to DC -- approval that appears to have come from the White House.
What's not clear is why Musk has suddenly decided to reverse course and begin working on his own Hyperloop platform.
