Is the idea of audiophile listening a dying concept as boomers die off?

Greed is the answer.  They seem to have  forgotten that you can't have an affordable flourishing market for Prorsche, Ferrari and Lexus, unless you have a flourishing market for VW, Fiat and Toyota.  Otherwise, it's all on borrowed time.

No. 
not in my experience. 

@kerrybh    +1   Horse racing has a very similar analytical structure(decision making) when compared to High End Audio!

Aren't Toyota, VW and Stellantis(Fiat-Chrysler) #1, 2 &4 as far as sales worldwide? What could be more flourishing?

I went to a private MBL event and the actual owners/buyers there were in my age bracket and slightly older, which is 40s/50s. 

Axpona, on the other hand, was likely more of a demo in their ~60/70s.

In my case, I had to plan months in advance to attend Axpona and blocked out a weekend.  Despite this, I still was only able to attend Friday.  It'd be very difficult to go to regular meetups or events, which I'd imagine is true for many working-age audiophiles.
