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.

Walter Isaacson sits down with Evan and tells him why the field has always been ripe with ethical questions, and how the COVID-19 pandemic pushed researchers to recalibrate their priorities.
