Only 20 years ago this was mention in sci-fi books and movies. Just think in another 15 years if not already, they can track you anywhere in the city. Monitor all your movements and conversations, with no place to hide.
Just watch the movie Enemy of the State starring Will Smith for an example. The tech exist now and has been around for awhile. Everything you do or type on the internet is being recorded. Only a matter of time before they record your voice for data processing, or is it here already (Siri).
Do you want the Red or the Blue pill? Is it time to move to the DarkNet.... ?
Darknet, deepweb, for 99% of us it matters not....your data is still be gobbled up in unimaginable ways.
I’ve worked on projects in the last couple years with AI/Machine learning that could identify people accurately based on such trivial everyday real life actions it made it obvious that “anonymity” is no more.
