Elon Musk was refused his request to be CEO of PayPal, and for good reason. Tesla and Space X are fancy speculative gambles or a luxury baubles the upper class flaunts as accessory at cocktail parties. Mansions that cost above a certain price point tend never to fall with the general markey trend because the entire purpose of these luxury goods is to "lose" money in overpaying as bragging rights by the upper class. Tesla is technology geeks' luxury mansion.
