> It is possible that some hypothetical super intelligent future AI will do something very clever like hide in a coding assistant and then distribute bits of itself around the planet in the source code of all of our stoplights and medical equipment.

That was part of the plot of person of interest. A really interesting show, it started as a basic "monster of the week" show but near the end it became a much more interesting plot.

Although most of the human characters were extremely one-dimensional. Especially Jim Caviezel's who was just a grumpy super soldier in every episode. It was kinda funny because they called him "the man in the suit" in the series and there was indeed little else to identify his character. The others were hardly better :(

But the AI storyline I found very interesting.
