What a significant difference. I'm afraid of it in the hands of Big Brother. But I would love for my phone to be able to look through my glasses and notify me "violent escaped criminal 30 feet away at 11 o'clock."

Except then it would also be able to raise notifications like "person affiliated with <outgroup> 30 feet away at 11 o'clock." Add syndication and people who wrongthink could be tracked down like pokemon.
