Richard Linklater filmed the actor who stars in Boyhood over 12 years from a 6 year old to a college youth. Matthew Sweet and author Toby Litt review the project and discuss growing up. Artist Cory Arcangel talks about his book composed from tweets and working in digital media. He also explores the themes explored in Digital Revolution at the Barbican Centre, which brings together film-makers, artists, game developers and musicians. As state schools across England prepare for the introduction of coding to the curriculum, journalist Aleks Krotoski and Benjamin Southworth - digital entrepreneur and former deputy chief executive of the government's Tech City initiative, join Matthew to discuss how - if at all - we should be preparing for the 'digital age'. Plus we hear another column from one of this year’s New Generation Thinkers, Jo Cohen, who asks whether we need to rethink the American Constitution, as the country recovers from its Independence day celebrations.
