In a way, this is a good step toward people writing applications that are good conversationally. Alexa does a good job of voice recognition but I agree that "conversations" are mostly about remembering the right wizard's incantation to make Alexa do something useful. Watching the (very simplified) demo, it's easy to see the seed of writing a useful digital assistant/Star Trek computer there but obviously someone(s) have a whole lot of work to do before we get anywhere near there.
