Even before Google demonstrated its frighteningly believable and controversial Duplex AI, artificial intelligence and machine learning was already a big topic on smartphones.

You might be tired of hearing about it every new phone launch event but, sooner than later, it's going to cease being just a buzzword. Pretty soon, "camera AI" will be something that all but the cheapest entry-level smartphone will have as a basic feature. Just like dual cameras.
