Chatbots and artificial intelligence: The challenge of making robots sound human. Ed Butler speaks to Bruce Lee, senior director of artificial intelligence research at Ant Financial in China - one of the companies developing chatbots to help customers. Justin Cassell from Carnegie Mellon University describes the challenges of making her chatbot SARA - the Socially Aware Robot Assistant - more friendly. And Jeff Hudson, CEO of cyber security company Venafi, argues that humans need to start giving robots identities, or risk being overtaken by them.
