In a 2014 CNN interview, Musk said he enjoys reading biographies, particularly The Biography of Benjamin Franklin, whom he describes as “one of my heroes.”
Musk said about the book, "it highlighted an important point which is that a lot of times, the question is harder than the answer. And if you can properly phrase the question, then the answer is the easy part."
Musk tweeted, “Worth reading Superintelligence by Bostrom. We need to be super careful with AI. Potentially more dangerous than nukes.”
Musk discussed how the book series Foundation by Isaac Asimov influenced him to build and launch rockets. This book spurred him to found SpaceX, the home to the Falcon 9 reusable rocket.
