Joseph Gordon-Levitt, AR sneakers, and a community of 500,000 friendly people

This week, Travis and Stewart finish up their Web Summit series of podcasts with a bona fide Hollywood star, Joseph Gordon-Levitt. We talk with Joe (as Stewart now calls him) about the creative, collaborative community he founded with his brother - hitRECord - and how he has not only managed to grow it to over half a million members but why everyone on the platform interacts in such a respectful way.   In the news, we talk about the difference between US and EU chatbots, what AI is going to do to marketers, and we sneak in a little retail therapy, augmented reality-style. Or is that mixed reality?
