Simone Giertz, YouTube's favorite inventor and robotics enthusiast, joins Offline this week to discuss the joy of building useless things and why adults should be able to play like kids do. She and the guys talk about overcoming perfectionism, the joys of "forward facing" activities, and how branding pastimes as productive vs. meaningless undermines the creative process. Jon and Max train their sights on Simone's most recent invention, and then they talk about ways to cut down on their screen time, from positive reinforcement strategies to phone cases with teeth and electric shocks.
