The past few years have shown that our infrastructure -- electricity, fuel, shipping, etc -- is more fragile than we expected. We're running on very thin margins, which is efficient!, but not very durable.

These systems should have a larger buffer for variation than what they run at now, and we should regularly exercise their flexibility. A chaos monkey for infrastructure perhaps. It will be a pain to deal with outages in normal times, but much less of a pain than being surprised by their inflexibility in the middle of some other crisis.
