content: Yeah well the people didn't care about security/privacy when computers were being developed, they didn't care when they first signed up for facebook years ago, they didn't care decade or so ago when all cars are now built with trackers in them (OnStar for example), they didn't care when the smartphone took storm. The trick to making progress for personal security/privacy is how to get people to sacrifice life's conveniences and accept hardships for the principle of trying to preserve nonexistent privacy/security. We lost the war. (Please prove me wrong.) Anyway, I don't think the brain implants will become that common. Besides, you can always fry them with a mini-EMP contraption.
