Imagine you use that last screwdriver, and a job needs to get done, and your car won't start so you can't get a new one at a hardware store outside of walking or cycling distance. And now you're unable to repair a vital system.
As I was writing that, I was just thinking of the recent Surfside collapse, what would would have happened if the regions data networks had gone down simultaneously (by chance). A major event two decades ago, cellular networks were overwhelmed and calls could not be made. I dare say we're more reliant on those networks today, as well as the Internet.
Not that I would expect it to happen, but it was just a thought.
