The machine recognizing you was the harder problem. That's the "Minority Report" stuff that people thought was in the _far far_ future that we don't have to worry about constantly.

Storing and using that model across various devices is trivial. So if we've done the hard part, the easy part is _definitely_ going to be done. There's no doubt about that.

States, companies that can convince the state that they somehow need the data (cough insurance companies) will, I repeat, WILL utilize it. And now, suddenly your premiums for this month have gone up cause in that ski trip you took last weekend, a camera noticed the lack of headgear for about 5 mins. That's the kind of risk the insurance company cannot take. Pay up.
