In the series Person of Interest, there's a scene where you can see racks of servers which allows to track everyone in a city (New York?).

When I first saw the scene I said: "This amount of servers is not remotely enough to pull something like this".

When I think of the scene now: "These amount of servers can do much more than the scene portrays".

I mean, most of the tech presented in the series is almost standard operations procedure via mundane equipment now.

Scary.

Subsequently in PoI we see two imperfect super-intelligent AIs let loose in the real world fight each other for domination and their objectives.

For me, it’s a question of when, not if this happens in real life.

		Person of Interest is really good. Unfortunately I learned too much about the lead's IRL behavior, and it's on my shelf of shows I'll enjoy once the involved parties aren't collecting royalties anymore. It absolutely takes people on a police procedural that drags viewers unwittingly into watching a science fiction show, and I'm totally here for all of it.

I believe they also pull this off with a fleet of PS3s, at one point.
