I work on the storage end of things, and although I have no connection whatsoever with government intelligence agencies of any kind, I do know that the capacity to collect information and the ability to absorb, coordinate, and act on it on VERY different things. I have heard from IT friends with different jobs that while CARNIVORE (or whatever it was renamed) stores almost everything that gets transmitted over wire, and stored, they are literally years behind in filtering and analyzing. I am sure if you get the attention of the Eye of Sauron, it can be accelerated on an ad hoc basis, and AI MAY make things more efficient (or just add another layer of complexity), it isn’t quite 1984 yet, at least not in Real Time.
AI still has a lot of bugs for sure.
We are probably five years or so before it becomes truly dangerous to our liberties.
