You can do a lot with that, but you could do a lot more with the AR/VR setup I've described. The assistants could see the body language of participants and take that information into account when formulating advice. (In fact, assistants could flip between multiple POV and gauge the body language of a sampling of the crowd or all of the key players.) If an assistant has a piece of side knowledge, like they happen to know on sight that someone's brooch was made by a famous craftsman, they could provide that as a conversation starter and help the executive score points. If an important person is walking up from behind, the executive could be alerted to end the conversation and so she can present her argument first.

As often noted around here, one can do more with more data. The AR/VR combination I've described would provide that additional data.

So you say. I was taking the conversation in a related direction. Somehow the idea that we can't talk about technological potential seems a bit out of place, even irrational for HN.
