On today's episode, Dan and Ian are delighted to welcome one of their favorite authors back to the show.

Cal Newport is a Computer Science professor, who has spent his career writing about the intersection of technology and culture in the contemporary digital age.

Cal joins us this week to talk about his new book, Digital Minimalism, which is all about the dangers and distractions of social media.

This interview covers a broad range of topics, including the psychology behind the "Walled Gardens" of social media, why Cal invited 1,600 people to go on a month-long "Digital Declutter", how we can develop a philosophy to improve the way that we interact with technology in our lives, and much, much more.
