These interfaces are good because they are asynchronous, all the good things about old-timey terminal stuff but without the session overhead badness. If I message back and forth with a bot in a way that accomplishes a goal over a longer period of time but doesn't depend on me maintaining my attention, phone line, internet connection, or browser state for that entire period of time then in many cases it is a superior experience. This is why I love chat-with-a-human interfaces on websites for support (although they mostly require maintaining browser state) because staying on a phone line absolutely sucks and the person helping you also doesn't have a real-time constraint so they often have the ability to get you better answers to hard questions.
