Ben Parr, Co-Founder and CEO of Octane A.I. discusses how companies and celebrities are embracing chatbots to interact with customers and fans. Parr explains how the rise in popularity of Facebook Messenger has enabled the chatbot industry to boom. He says the young generation isn't on email anymore, so companies need to catch them on their social messaging apps. Plus, his new book, "Captivology," explains the three stages of attention: immediate, short, and long. He says companies need to start at immediate, and work their way up with customers. Parr also talks about how Sheryl Sandberg views attention, and how to cultivate it within a workplace.
