The bigger problem is that you essentially need to host somewhere a database with personal information of everyone you met, including their names, biometrics and private details. Nonconsensually. And it has to be accessible through the internet.

Honestly, just take notes and reread them sometimes, maybe?

You already collect data on some of the ppl you meet (messages, contacts, LinkedIn connections etc).

But the face recognition, memory of interactions etc should stay on device. That why I said I don’t want it to,take pictures I have access to.

		I can't have a message or a LinkedIn connection without other person registering with messaging app or LinkedIn, willingly. When they setup LinkedIn or message me, they are fully aware of the fact that I will either access or receive that information. Not comparable. >> face recognition, memory of interactions etc should stay on device It can't be processed there, chip too small. And physics don't allow us to make chips smaller anymore. I wonder, though, if it could be hosted on a phone and processed here. Not realistic for current smartphones, but if we talking about theoretical, it's would be a neat trick. I can imagine a future device that has three parts: lightweight glasses with HUD as a thin client, a glovelike input device to track your hand, and a small box you put in your pocket/bag.
