Elon Musk, by Walter Isaacson: My Book Summary & Review

Elon Musk

By Walter Isaacson

Elon Musk is most likely the most influential and productive innovator of the 21st century. Isaacson, who spent two years shadowing Musk, gives an intimate look at Musk's life from his troubled childhood in South Africa to his controversial takeover of Twitter. The book does a phenomenal job at detailing Elon’s private life, his visionary goals, and his habit of “shooting himself in the foot” with his risk taking and questionable antics that has made him such a polarizing figure.

Isaacson shows Elon Musk as a very complicated person who isn't just a simple hero or villain. Musk is portrayed as an incredibly smart innovator who wants to make big changes in the world, but he's also someone whose intense personality can cause problems in his personal and professional life. The biography digs into Musk's life, highlighting both his successes and his failures. It reveals how Musk's unique way of thinking pushes him to tackle challenges that most people would consider impossible, showing readers the complex mind of a modern-day pioneer who isn't afraid to take massive risks to achieve what most would call unachievable.

Elon constantly has his mind on the future, and not just on the near future, but on the future outlook for humanity. 

"Human consciousness , Musk retorted, was a precious flicker of light in the universe, and we should not let it be extinguished... Musk explained that his reason for building rockets that could go to Mars was that it might be a way to preserve human consciousness in the event of a world war, asteroid strike, or civilization collapse."~ Walter Isaacson, Elon Musk

Elon Musk in the Future

Elon is a huge believer that the product needs to be awesome. But it’s not just the product that needs to be great, the means of making the product needs to be extremely efficient.

“It’s not the product that leads to success. It’s the ability to make the product efficiently. It’s about building the machine that builds the machine. In other words, how do you design the factory” ~ Elon Musk

One of the most fascinating things about Elon, to me, was the way he made decisions inside his companies. He handled many of the problems himself that would typically be managed by HR departments or a head of engineering. Musk's hands-on leadership style sets him apart from typical CEOs. For example, Isaacson describes how Musk personally worked on the factory floor at Tesla during the "production hell" of the Model 3, sleeping on the factory couch and making real-time engineering decisions.
