With Google Duplex I'm sure we're heading towards a future where a computer is going to be answering all our customer support calls without us knowing about it.
Google Duplex was a cool demo but those intents were quite well defined. There is a handful of form slots they are aiming to fill where they can enumerate all the entry points to a conversation as well as misinterpretations. I do agree that this is the direction we are going, however since Google Expert is a broad term tackling a much bigger search space, I'd expect it to work differently.
