I consider myself to be a very brave entrepreneur, and I have had my own business for most of my life. However I have never seen anyone like Elon Musk, he is the most amazing #1 entrepreneur worldwide and has risked his all his money multiple times with his various different start ups. If any human can figure out how to live on Mars, I bet it will be Elon Musk. Now he is building a network of tunnels under Los Angeles to elevate traffic congestion.
It is always very interesting to watch and learn when Elon Musk makes a new video.
