The IA advance which is most obvious to me (yet somehow not yet a reality) is the nomenclator.<p>In Rome, a nomenclator was a slave who remembered people&#x27;s names for you, and as they approached would whisper to you that this is Gaius Tullius Castor, his wife is Flaminia, his eldest boy is Marcus, and he owns beanfields.<p>A Google Glass camera on your eyeglasses and a speaker in your ear, hooked up to Facebook&#x27;s face recognition and social web, can tell you a quick precis of who you see across the room before they get to you. Add a touch sensor in your pocket or on a ring for unobtrusive control, and a mic to pick up your annotations or commands, and you&#x27;ve got a product that should be a major hit by the second generation.
