What is it like to shadow Elon Musk for two years? To sit courtside as he builds a rocket? Or tears apart an engineer? Or couch surfs at the homes of billionaires? And how on earth do you make sense of it all? Walter Isaacson is the biographer of giants: DaVinci, Franklin, Doudna, Jobs...and now Musk, former enfante terrible, rocket launcher, electric car innovator, and Twitter—er, X—disruptor, to put it gently. In this four-part series, author Evan Ratliff (Mastermind, Longform Podcast) sits down with Isaacson to draw out the behind-the-scenes stories of this epic biography, and what the writer has learned as an outsider inside Silicon Valley.   Listen here or on the iHeartRadio app.  See omnystudio.com/listener for privacy information.
