IMHO, the main reasons that aircraft engines require so much fiddling is
two-fold: one is that aircraft engines operate at constant settings for most
of the time they are on; another is that improvements cost big bucks in the
form of certification costs, bucks that most pilots won't pay when the
current (albeit ancient) technology suffices.

I suppose that makes sense. I know that I'd rather have older
technology that is certified than newfangled technology that isn't, at
least for aviation (and for many other things, but I guess I'm getting
tired of seeing complex, poorly designed systems fail so often).
