Dude has started THREE iconic companies, two of which are in hard-ass, "real engineering" fields that were previously believed to be impenetrable. This is most certainly not a fluke. Henry Ford is nothing to be ashamed of, if you can pull it off.
Musk is no Henry Ford. Henry ford success is that he built an extremely profitable company that changed the way people travel. I am sure PR investments had less to do with it.
Musk is a guy who spends money to promote himself everywhere. Tesla is a rich people's car subsidized by poor people's tax money and the company is not making a profit and is unlikely to make a profit in future either. Even if it does there is nothing groundbreaking about it that Toyota or Ford can not replicate without much efforts.
SpaceX is good company but hey it isn't profitable and has not achieved anything major that NASA or Blue Origin could not have given the investments.
An hyperloop is going to be a regrettable experience for everyone involved.
All three of his companies are piggybacking on government money and have not made our lives better than the alternative.
Oh, I didn't know companies had to be profitable from day one, I'm sorry. Maybe you should apply for a position of Musk's business development advisor, clearly you know business side of things better than he does.
And Tesla is about a month and a half away from unveiling its "non-rich" people car, and they used Model S revenues to corner the market on lithium ion batteries in the meanwhile.
Space X is the only US company that can currently deliver shit to ISS. Soon they will also be the only US company that can deliver people to ISS, and the only company in the world to use a reusable first stage. If that's not an achievement in your book, then I'm not sure what a real achievement would look like to you.
What have you done with your life?
