I read this really really long article in I believe The Atlantic about the need to simplify the nature of software in distributed 'coding module'* environments like planes and cars where you've got code that controls all aspects of the whole and it keeps getting more and more complicated and eventually becomes impossible to debug. Anyway, they talked about these hackers that pretty easily figured out how to hack into individual vehicles and have complete control over the vehicle while it was being driven. They also showed how easily they could have made that initially hacked vehicle into basically the control center for controlling every other vehicle of the same make and model. In other word,s had they wanted to have 40,000 Ford Explorers simultaneously crash by veering hard to the left at full speed, it would have been easy, breezy, beautiful. Hackers are smart. *my phrase, not theirs
Here's the article. Could have been way way shorter, but still interesting: https://www.theatlantic.com/technology/archive/2017/09/saving-the-world-from-code/540393/
