Journalist Nick Bilton talks with Recode's Jason Del Rey about his new book, "American Kingpin." It tells the story of Ross Ulbricht, the programmer and "criminal mastermind" who founded the Silk Road, a notorious online black market where everything from drugs to guns could be bought and sold anonymously. Bilton, a special correspondent for Vanity Fair, also talks about why he left the New York Times in 2016 after more than a decade there, saying he didn't feel challenged by the newspaper's predictability and rigidity. He also argues that, contrary to what the Facebook CEO claims, Mark Zuckerberg is likely running for president — or perhaps planning some other major change that necessitates a heavily photographed tour of the United States.
