Gives some insight and a sense of safe close view of this rather unpleasant business tycoon.
Musk is not a guy I want to meet in person.
I rate starship as a labour of love by the employees, the other enterprises are, troubled. Compelling reading even so, with a good skeptical distance provided by David Icke in his recent book "The Reveal".
I have read other books by Walter Isaacson. Always does a very thorough job of what motivates the subject and how they succeed against all odds.
Highly recommended.
