Perhaps a couple strangers would hear a few words but don't know who you are. If police or other state agency are pervasively watching, listening, and recording, I think you would agree that is quite a different situation.
Imagine you are walking down the street talking to someone either on your phone or in person. Facial and voice recognition are very advanced these days.
I didn't find any analysis here of what these companies are doing with all this location data they are collecting. The consumer gets some detail of single devices which they can see on a screen, but the mother ship is collecting a ton of detailed location data from every device that they can run through their advanced computing to refine into predictive products or advertising. This is the bigger story to me.
