Fascinating book about a fascinating, dangerous giant of a person. This is a long book, but Isaacson's very short chapters and the constant drama of his subject make it go very fast indeed. So Isaacson makes the book easy to read. But the Musk quite frankly is a like a Greek God (and that is NOT flattery).
But what kind of giant? There is a terrific intelligence mixed with a drive or mania, and consistent physical energy. And it is focused on *several* visions at once (space travel, electric driven ecology, AI, "civilisation"). In this regard he is greater than Steve Jobs, Zukerberg, Besis, Gates, Brin, all of whom are amazing (not all nice!) people.
Isaacson never really digs deep into the character and morality of Musk. Musk's vision of future threat - is it anything more than an intelligent reformulating of childhood space comics? For all Musk's reading, we see no evidence of intellect. His emotional complete un-intelligence seems permitted because he gets incredible things done. His treatment of women (shoddy) and of children (loving, sporadically) is not of a modern man but a great medieval baron. This man is a colossus, creative, but also dangerous. He is akin to Joseph Stalin. When young, Stalin was energetic in his cause, ruthless too, cunning, but cultured (yes). But later in life became paranoid, and commanded the killing of even more people. No - Musk is not in the trade of killing, and the analogy has real limits. But Musk's negatives will become much more apparent as he enters the public arena more and more, and his life revolves around engineering less and less.
Read the book now. So when The Giant slides down The Beanstalk, you will not be surprised!
