Oh yes, look at Twitter right now , Elon Musk is on his way to do the same , not for money, but for power..and in a very short time too..
Twitter aside what Musk has done with Tesla and SpaceX is nothing short of astounding. When he started both ventures the know all would have given him zero chance. No one had broken into the car industry in many decades. As for private launchers and contract hauling to space, you would have been sent to the rubber room.
I for one very confidentially predicted tesla would be bust in 2019 and GM or VW would buy the carcass.
As for Twitter - really who cares? It's an internet thing and they come inevitably go. It will be replaced.
SpaceX and Tesla represent amazing engineering and hard tangible goods.
I stand by me prediction the boring company will be a bust but I will give the guy credit where credit is due.
