It's taking me a few minutes to come up with something beyond, "That's patently damn absurd!"
But... I guess like many things, nobody would write it if somebody didn't buy it. My first thought from the formatting and related image is that this was sensationalist crud from a few decades ago. After all, that machine has a 5 1/4" floppy... but they're talking about Amazon.com, so it's not that old.
Sure, there have been instances of software failures killing people, but wholesale madness probably isn't going to happen. Most critical systems, like traffic lights and railroad signaling, have safety systems that back them up. Thus, you'll never see an intersection with opposing lanes having a green light. Even sprinkler systems rarely activate all at once -- that requires a special system known as a "deluge" sprinkler setup. I guess it just looks cooler on screen if they all go off at once.
Granted, Therac-25 is a memorable example of that being improperly designed. We've also seen viruses like Stuxnet that have caused some chaos for certain folks. However, "coming within 2 digits of a 37 digit code to launch nukes at five American cities" is complete bollocks. I mean, if they came within 2, did they know and tell us? Was the military aware of all the codes they tried?
Jack Sparrow: It's the Pearl.
Prisoner: The Black Pearl! I've heard stories. She's been preying on ships and settlements for near ten years. Never leaves any survivors.
Jack Sparrow: No survivors? Then where do the stories come from, I wonder?
If you're going to die in your home from your own technology, it's going to be because you have lousy wiring or some malfunctioning device and don't have smoke detectors (granted, this incident happened because of hot coals).
There's nothing your own PC can do to blow itself up. Unfortunate conditions can cause Li-ion batteries to blow, but not from software (again, interlocks unless the designer wants to go bankrupt). However, those critical interlocks are a consideration for industrial design, but more so for mistakes than for malfeasance. The idea that hackers are going to turn your computer into a bomb, though, is outright scare-mongering of the most pathetic kind.
