I vote a resounding YES! When I was a kid there were a couple of dozen
very knowledgeable adult hams (amateur radio operators) in town and I knew
plenty of kids and teenagers that were seriously interested in electronics
and many more than were intersted in mechanical things such as automobiles.
Now I know exactly ONE teenager that's remotely interested in electronics
(and he only knows enough to be dangerous!) and perhaps two that are
interested in mechanics. And this is in a town that's at least twice as big
as the one that I grew up in. And as far as finding a knowledgeable ham
goes you can just about forget it! There's ONE in town. The rest just buy
prebuilt packaged radios, plug them in and start talking. They're even
less knowledgeable than the CD operators were in the 60s.

I think the question boils down: Are we losing any knowledge as each
generation passes?
My instinct would say "no",
