>I wouldn’t put my money, time, or talent in the hands of someone who takes me for a fool.

When Musk said he makes it "open source" and "invites everyone to contribute" I thought he meant exactly this. People finding flaws and ways to do things better so in the process the flaws are eliminated and you end up with some workable design.

I don't understand why some people react arrogantly, or feel offended with the hyperloop design I have a suspicion that if Musk wasn't labeled as "billionaire" people would react differently.

He kind of lost me with his comments such as the one above, but that doesn't change anything about the quality of his arguments.
