[AT] Generator--doing funny things

Well, that too, Steve, but if you'll pardon the 16-cylinder wording--
there's been a paradigm shift in how all machines are controlled.  These
old farm tractors that we work with were controlled with linkages,
gears, wheels, and handles.  Today's monster machines are miracles of
electronically controlled hydraulic systems with up to seven pre-sets on
the lift system so you can "hitch and go" to instantaneously change over
from one attachment to another in a minimum of time.  An operator can
have his fields analyzed as he drives through them and have weed or
insect infestations recorded by GPS and treated automatically the next
time he drives by.

And it's just as bad or worse in any other field you want to look at.
We can't do anything anymore without putting a microprocessor or two
inside it.

I'd better stop before this goes from being a commentary to a soap box.

So your saying that most of todays engineers like things that are
silicone "enhanced"...
