Does Kara ever get sick of talking about Elon Musk? That’s a question Nayeema asks today, and they both agree: as exhausting as he can be, Elon is a defining force in business, media and innovation. So today we turn to the titan’s biographer: Walter Isaacson. He’s written the book on everyone from Leonardo da Vinci to Steve Jobs, and is now deep in the Elon Files. 

Taped in front of a live audience at the New Orleans Book Festival, Kara and Isaacson discuss whether Elon is driven primarily by narcissism or mission (aka the “prick to productivity ratio”), how Elon does and doesn’t compare to Steve Jobs, and how Isaacson approaches his job as a biographer of some of the world's biggest personalities, both alive and dead.
