To perhaps add a dimension to the issue, imagine that one day you woke up and the roads were not functional. Many people would have a great time, as long as they knew the roads were going to be functional later that day. If it turned into a longer problem, the disruption would have vast and unpleasant consequences.

We do not yet have an awareness of our dependence on technologies, nor of how fragile those technologies can be. If someone had suggested years ago that perhaps we should prepare for a disruption in say, the egg supply, that would have provoked laughter. And jokes like, well I really don't like eggs. Or what about toilet paper hoarding? Given just those two events alone, one might decide that disruptions are at least somewhat of a possibility. That our past assumptions of an unending supply of goods and services might not hold in the future.

It is a funny comment, and there are several dependencies I personally would not miss. Until I did.

Personally, the interesting concept is resiliency in general.
