The vibe around smart glasses is so weird: Governments and businesses can record in public, which is right and proper, but if an individual person records what they see, that's wrong and creepy.
The original assumption behind CCTV was that it's recorded but realistically never seen, or maybe seen by one person staring at a bunch of screens at once. That's what made it acceptable. Of course this has changed drastically, but CCTV basically got grandfathered in in most people's minds.
What cloud recording is capable of determining... is absolutely limitless. I think this is what makes Flock so scary / "different."
