This article reminds me of the "fire sale" in Live Free or Die Hard - it starts with a traffic jam / crashes triggered by traffic light manipulation, and of course escalates from there. I always felt like the movie was predictive programming for a real-world plan.
Do you think this is how the end starts - a massive hack / shutdown of systems everywhere? We don't need nukes or an EMP when everything we have relies on a vulnerable system of interconnected machines.
