Elon Musk isn t building a car company, a solar company, or a rocket company, he s building the infrastructure to colonize Mars. SpaceX, Tesla, and SolarCity are the infrastructure required to power Mars, and then they just put it into Tesla. Elon's done a masterful job of saying what are the big pieces required to colonise Mars at scale, what problems require top engineering talent, and I will support companies to do this. Most entrepreneurs should really think about what is your true north star of what you re trying to build and how do you reverse engineer the pieces in the sequence for you to do that?
