I don't think it is yet appreciated how much it directly and indirectly attacks infrastructure, distinct from most disasters.
They're partially because supply chains are composed of people in small pockets of air.
It is difficult to prove the safety of any ship in the world right now. Or, say, any elevator.
But, by happenstance, our defaults align well with its spread.
Another is being able to recognize that threat and pivot, very, very quickly.
Much of it is, unfortunately, also a small pocket of air.
And now the HVAC details really matter.
The somewhat good news is that we're better equipped to quickly pivot infrastructure than we've ever been, thanks to changes in how it is constructed which happened mostly very recently in human terms.
