It is a long book, like any other biography, frankly. But it was amazing to read about one of the newer polymaths of our age, understand his vision, and know his background story in a bit more detail.
Pretty straightforward. No complex narration. Vance wrote that he had interviews with Elon himself, so I figure the story is not unrealistic.
The book narrates Elon's early life in South Africa, his move to Canada (and later to the States), and how he established his business ventures: Zip2, PayPal, SpaceX, Tesla, and others.
One particular feature of Vance's writing that I liked was how well he could convey Elon's emotional state as his rockets (SpaceX) kept failing and collapsing. And how he didn't even care about money as he was monomaniacally focused on his intellectual ambitions.
A good read, but a bit long.
