"Q. What will that look like in the future?Facebook's Yann LeCun Discusses Digital Companions and Artificial Intelligence (and Emotions) - NYTimes.com
A. I’m not saying this is a future product, but a way to think about this if there is an intelligent digital companion that allows you to think about things in a new way, the way you interact with friends, expand your thinking. There will be a single point of control that knows and respects your private information.
This kind of A.I. will come progressively. In some ways, parts of this are already there in the Facebook News Feed, in Apple’s Siri, or Microsoft Cortana. They are shallow now, in the kind of interactions you are having. They are somewhat scripted."
