One thing I've always loved about automated chatbots, is the analytics you can get to see how the answers are performing.

Most companies don't spend the time thinking about if their support staff are answering questions via chat effectively, they just care about volume and time-to-response.

AI seems to be allowing us to focus on the quality of the interaction, which is great (and slightly ironic, given the concern that computers wouldn't be as good at communicating as us!)
