Yeah, the world could use more people like him. He's mostly not motivated by the money. After making $1B from the PayPal exit he could have just retired and bought a yacht or an island. He wants to de-carbonize transport and colonize Mars. Both to give humanity a better chance at surviving into the future.

That's three billion dollar companies so far and counting. Is there anybody else who's done that? Not to my knowledge.

He quite likely has some kind of savior complex, he's quite literally trying to save the world.

A fascinating and incredible human being.
