This week, Travis and Stewart discuss the perils of unlocking phones with your face. Let's just say that Stewart isn't a fan. They then talk about Snapchat's newfound usefulness, location-based marketing, and a big raise for a geographical data company. They then interview Amit Walia about A.I., where it is making a real difference now, and what is going to happen next. Don't miss one of the smartest interviews of the year.
