Everyone is so scared of these invisible bad guys going after infrastructure, such as power plants, dams and water treatment plants.
Let's think of something even more important. Let's think Wonder Bread. A few lines of code, and *bam!*, you've shut down the production line on a factory that's used to churning out 10,000 loaves of bread per day. Do that for a sugar plant and see what happens. How about an operation that makes chicken and hog feed?
Everyone is so focused on the big stuff. Lemme tell you, if the bread plant even loses connectivity...it shuts down. Because it doesn't know how much of the product to make! Better to not make anything, and endure a temporary shortage, than to make too much that will go to waste.
You don't have to worry about the sewage treatment plant getting attacked, when there's not going to be anything for people to poop out.
