A friend of ours is fascinated by Elon Musk and like you said, he is very innovative, but he has his hands in too many projects. Don't half ass many things, whole ass one thing!
What he is doing with Space X is amazing, but his energy should be spent on how he can better the world with innovative technologies. The Boring Company will help the first world and developing countries with the inconvenience of traffic jams, but making a product or service that can be used for everyone is what he should be doing.
