Give me a phone with a keyboard I can touch, and an artificial intelligence app to talk with Ben Franklin. They used to make the first half of that request (see my picture below), and now they're making progress on the second. Amazon is trying to get Alexa to the stage where it can have a 20-minute conversation like (and with) a person.
I don't think anyone cares about talking with the "personality" of Alexa, but I think it'll be interesting when they can start using the volumes of writing from people like Benjamin Franklin or Abraham Lincoln or Winston Churchill to create artificial-intelligence personalities based on those historical figures. I'd call them "personality engines" (in a nod to "search engines"). And I think it would be amazing to "talk" with AI personalities based on those people.
