Elon Musk is the brand investors invest in, not tesla, not spacex. As he says, he is the pot of money - he is the core driver.

I personally applaud his bravery, changing the established order is hard and carries great risk.

He is the real consortium of products and can shift money between these industries at will.

The risk here for all of his companies is that he is building a house of cards, one company collapse could bring it all down.

Or if they all succeed, he may become one of he most powerful entrepreneurs in history.

Which is his real 'secret plan'
