Once things start rolling downhill in that direction on a scale large
enough to cause problems, you are very likely to see things go like
Syria. The main problem will be the food supply failing because it is
totally dependent on the energy supply. I don't know how far things
will fall back, long way would be my guess.

Agreed. There are a lot of files around. I have also ground a really
nice knife out of a file, but then there are a lot of knives around
too. Big fall in the population and there should be knives around
that keep people from needing sharp rocks for hundreds to thousands of

Robert Heinlein was a major influence in my life. There is a list of
skills in _Time Enough for Love_ "A human being should be able to
change a diaper, plan an invasion, butcher a hog, conn a ship, design
a building, write a sonnet, balance accounts, build a wall, set a
bone, comfort the dying, take orders, give orders, cooperate, act
alone, solve equations, analyze a new problem, pitch manure, program a
computer, cook a tasty meal, fight efficiently, die gallantly.
Specialization is for insects."
I can, and have, done most of those. Those I have not, such as "plan
an invasion" just have not come up in my life.
I have, however, done every single step in making bread. For a few
years I made virtually all the bread the family ate. (It was a sink
for the excess eggs from the chickens and ducks.)

As a kid I was known for doing this. The late and very much lamented
Hugh Daniel used to provide such opportunities frequently. He was
exceptionally good with kids and ran "take it apart" sessions
frequently at science fiction conventions. A favorite for many years
was disk drives.

Exactly. What is a kid going to learn taking apart a solid state drive?
