It seems to me self-evident that *someone* does
understand how any one of those chips works -
they just didn't tell the rest of us.

In the "old" days, DEC used to produce technical
manuals for pretty much everything and the manual
was shipped with the product. If you bought a
DSV-11 you got the tech manual and an installation
manual etc. If you go slightly further back, to the
early 1980s, you were almost certain to end up
with schematics too. This meant someone had to pay
to get these items produced and that someone was
the customer. Some time in the mid 1980s, someone
at DEC realised that the customer base had shifted
slightly and most customers had no use for these
manuals. So they were not routinely shipped, but
were available if you paid for them. These days
the number of customers who would order such manuals
is much smaller so producing them is rarely cost-effective.
(They are pretty expensive to produce properly).

I'm not sure that car mechanics have any better a track
record than the average motorist :-)

I think modern cars might be a bit more complicated
than those from say twenty years ago, but only because
they have more in them to go wrong. Getting hold of
diagnostics from engine management units seems to
be pretty hard, but it's not often required.

I suspect that C has actually gone up (or your standards for
the entry bar into C have). There are many more people around
now (that I know) who can fix their PC or fix their radio
or fix their car. (Maybe the number for "fix the car" is
no greater in my case, since most of the people I knew
n years ago could not afford to take their car to the
local garage for a service or something minor like
changing the brake pads etc).

"worse" being that they give it away to someone like me :-)
