Most AI assistants can't really hold a conversation. They're fine with I-go-you-go dialogue, but most humans aren't quite so timid -- they know when to interrupt, and when to restart chat when there's an awkward pause. Microsoft wants to fix that. It just upgraded its Xiaolce chatbot AI with "full duplex" conversation that lets it start speaking when it's listening to what you're saying. As it can predict what you're likely to say next, it knows when to interrupt you with important info or say something more when both sides suddenly go quiet. Think of it as that friend who knows when to speak up without being overly rude.
