75% older than 35 is actually somewhat startlingly significant

I realize we have an international audience that votes, but US participation at AC is in the high
80%-range last time I checked - so most of the respondents were likely Americans.
Anybody wanna' hazard a guess what the median age is (according to Census 2000) in the U.S. today? Try,
35.3 years - up from 32.9 years in 1990. That is, fully 50% of the US is over 35.3, and fully 50% is under 35.3.
Coupling that with the likely fact that actually actively using the internet is more likely to be a younger, rather than older, participant (greater familiarity with technology that comes with youth is a given, isn't it?) and you have a very scary figure.
If 75% responded that they were over the age of 35 doesn't
at all bode well for the future health of 2 channel audio. We are likely to have far fewer offerings in the future, and higher prices, due to less competition and economies of scale for manufacturers. Higher prices and less offerings is part of a cyclical, repetitive spiral to doom.
Possible younger 2 channel enthusiasts, with less disposable income, have other, better value, alternatives to spend their discretionary dollars on now. Without them involved, the rest (literally) die off

This process has already played out in vinyl, where under-$300 cartridges and under-$1500 turntables (I mean, come on, you can get one helluva' big and beautiful flat screen television now for $1500.00 - that's a whole lot more
apparent value than a similarly priced turntable) are now thought of as 'budget'. The only manufacturers that offer real budge faire under these prices tend to be older, well-established makers that have long ago paid off the tooling costs for new products and can offer better prices than competition because of it. It is only because there is still significant competition from 70/80's gear that new prices are likely kept somewhat in check. If that old gear starts drying up or becomes increasingly mechanical faulty and or parts availability evaporates - a lot more vinyl enthusiasts will be lost who won't pay the premium prices for new gear.
High Fidelity, at least the 2 channel variety, is indeed dying...as it's participants likely are, as well. But, it's a long, drawn out process that won't likely see it's statistical end for several decades into the future.
We ought to be real nice to one another...we are
mostly last of a dying breed
