At last year's I/O conference the star of the show was Duplex, a conversational AI assistant that sounded just like a human and was able to call a restaurant and book a reservation.
It was truly incredible, even if Google has not yet delivered such a futuristic experience in the version of Duplex that's currently available.
But given that artificial intelligence is one of Google's primary areas of focus, expect Google to showcase lots of new, eye-popping demos that show the technology's potential.
