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.
