I've heard of a pretty amazing, advanced technology called a generator. I've
heard of another one called a hand crank.

You have presented a scenario where dependence on technology is
nearly complete, but I do not believe that is a prerequisiste for
using technology in disaster situations. There is a difference between complete
dependence and partial dependence...or even no dependence, but simply
"assistance." There is a reason the French adore their pigeons as I
recall....it was an ingenious solution to being cut off from the rest of the world,
and I see no real difference between turning to pigeons to carry messages and
turning to a temporary, small, mobile network when phone lines and electricity
are down, the bridges are out, and no help is coming. It's amazing what a
satellite phone and a generator can do.
Now, I will happily grant you that having an entire, large scale deployed
system consisting of thousands of systems requiring terrabytes of data transfer
and on which everything else hinges is almost certainly doomed to fail. But
that doesn't mean that all technological systems are doomed to fail. They are
but one tool in the toolbox, and the more tools one has, the more adaptable

A close look at the living conditions of those who did not survive might protect
against too strong a belief in good race and class relations in America.
Assuming you were referring to levees as technology, then it
might also protect against a belief in a technology that has been consistently
and repeatedly shown to be failing and/or a belief in the efficacy of the Army
Corps of Engineers. But I fail to see how a concern about those things somehow
expands itself to include all technology, period. You are taking some specific
technologies and expanding their failures to all technologies.
