Elon Musk by Walter Isaacson
Elon Musk grew up in South Africa, yet his roots their were fairly shallow, with ancestors in US, Canada and England. His father Erol was quite a character and divorced his mother when Elon was young. He initially lived with his mom, but later decided to live with his dad. He has since had a full falling out with his dad, especially after he had two children with a woman that was previously his stepdaughter. His father was also an accomplished engineer with many business endeavors. Musk had many interesting characters in his family history.
As a teenager, Musk went to America. He has since claimed Canadian and American citizenship. He went to school, was involved with computers and started his own software company. He went from that to others, including X.com (which merged with Paypal). SpaceX was his pet project to get people to Mars. Other parts like Starlink are part of that. He became involved with Tesla early on (with a messy discussion of who were the founders). He later founded OpenAI, though had a falling out with the leadership.
Musk has a mission of preserving humanity. Tesla would help stave off global warming with electric cars. SpaceX would bring people to Mars as insurance policy against a global catastrophe. AI efforts are meant to control AI so that it does not control us. He also feels it is important for talented people to reproduce to propagate humanity. Like Bill Gates he has self-diagnosed Aspergers. He works hard and expects every else to put in extra effort like him. He is not somebody known for work-life balance. He is willing to buck the trend. Everything done must have justification. Just because it was done before, does not mean it should keep being done. He has become the world's richest man and first trillionaire, yet has lived at times like a pauper. At times he doesn't care how people feel about him, while at others he finds it extremely important.
