ummm...computers will be the first to disappear. You can't fix

Of course you can. You can't fix the individual chips, but a well
equipped kitchen and paint shop (plus a soldering pencil) has all
the tools you need to replace the components on the circuit boards.
And where are you going to get those components? And where are
you going to get the power to run the system?

Well, since we were talking about an ark situation, presumably there
would be a carefully selected stock. But failing that, the most
efficient storage method is probably to have some number of working
computers. As they fail, you cannibalize to keep as many working as
you can.

If you are trying to run computers, then you still have a source of
power. If you don't have power, there's no point in fixing the
computers any way. But in that case, computers weren't the first
to go. They went along with everything else that required power.

How do the power generators and distributors work? don't they use computers?

The most basic power generation that greenys currently use dont.

To
make things easier, you could stock older tech computers whose
components are easier to solder/desolder, i.e., QFPs instead of
BGAs.
Most of those doughnuts are in the dump.

Most, but most is a majority of millions. There are still thousands
kicking around which could be stocked in a survival shelter. And
enough non-BGA components around, that if one were really planning,
custom systems could be built. The FPGAs are still sold in QFP
packages as well as BGA.

Given the scenario, anybody who spends their time fixing computers will get no supper because s/he hasn't gathered it.

Wrong, they get paid in the food others have gathered,
just like the priests and blacksmiths etc did in the past.

Bearings may also be made from oily woods, and often work for
ships propeller shafts, even today.
I don't think I've ever seen any wood bearings. Were any
bearings used in sailing ships (now that I'm thinking about
this)?

Yes, wood bearing were used in sailing ships, in particular along
steering shafts and later for propeller bearings.

I don't remember seeing shafts in _old_ sailing ships.

You didnt look in the right places. Anything that has
the traditional wheel for steering has to have them.

We still use lubricated wood bushings. Maple has an excellent
capillary structure to capture and yield lubrication. It is also
hard. It is especially good for wet conditions. It has about half
the strength of bronze, but is more economical and lighter.

I'll be looking for them now.

When sailing, all ships have a bearing.
I'd write more, but the sun is well over the yardarm, and it's time to
go stand in the rhumb line. ;-)

I could go for some rum. I should get in line too.

But if you drink too much and then try to helm the ship, you will have a
hard time keeping your Bering Strait.

Pat will often rope folks into his sense of humor. It's hard knot to
respond. But the schooner we stop, the better.

"Rope"? It sounds like you're three sheets to the wind!
