The discussion about emergencies and complex systems reminded me of
Lister engines.
They're slow-speed diesel engines of very old design. Usually they are
used as backup generators.
They've gathered a considerable following, as evidenced on websites
like this one:

There's almost something steam-punky about them!
Some might wonder why anyone in his/her right mind would bother with
such old technology, particularly when much smaller, lighter, newer
generators are available.
One reason I can see is that in an emergency situation the big Lister
can be fixed with minimal tools and parts. Another is that even a small
one isn't going anywhere unless it's on a trailer. Still another is the
ability to buy and fabricate parts - everything is so big.
The performance achieved is pretty impressive, once all the bugs
areworked out.
What this has to do with Amateur Radio is:
1) In an emergency, old and simple has its advantages. This goes for
radios as well as engines
2) No RFI!
3) The Lister isn't too fussy about fuel; I suspect one can run on
diesel, heating oil, biodiesel, vegetable oil (in a warm climate) and
maybe kerosene (in a cold climate.) Our radios should be as flexible.
4) The Lister is simple enough that a reasonably-knowledgeable non-
professional can do whatever is needed to build and maintain a genset
based on one. I think the same should be true of Amateur Radio rigs -
maybe not all of them, but certainly at least some. While they may not
be as fancy or "state of the art" as some, what matters is they work.
