Billionaire Elon Musk is the CEO and product architect at electric vehicle maker Tesla. He is the founder, CEO and lead designer of the aeronautics company SpaceX. He is also the founder of The Boring Company, a tunnel-digging business aiming to solve the problem of traffic congestion. Oh, and he's also an advisor to Open AI, a nonprofit organization aiming to ensure safe artificial intelligence.

He is, undisputedly, a very busy man.
