Where will technological privacy be?

This documentary goes deep in different technological possibilities like a hidden 3d face cam in your mobile, Ring doorbells and what they do next to filming and listening, led streetlights who can follow you and so on. So how to keep digital privacy?

I don’t know why the post was flagged, because the fact based technology of the content in this documentary was clearly not seen by the one who did give the flag on his/her made-up opinion.

The legit question is, on what level can you maintain your privacy as you watch the technological development in this documentary?

Their Vision, Your Future examines the digital prison.
