Did vinyl sales just hit the proverbial brick wall?

I agree with @bdp24 that the article is poorly researched and draws dubious conclusions.

However, the vinyl resurgence will peak and start heading down soon. Yes, the boomers passing away will make a big difference. But it is also about technological progress in digital. CDs or even stored files were not remotely competitive on a sound quality / cost effective basis. That has been rapidly changing over the last five years.
 

Right now, in general, analog still wins in the budget and ultra high end categories. But in the, say, the $50K - $200K category, it is very competitive SQ-wise… and if you do only one and put your money on streaming, then the sound quality is better and the cost of music goes to almost zero, and you have access to millions of albums. That is such a value proposition that folks new to the high end would be crazy to ignor. 
 

So the writing is on the wall. It’s over… except for nostalgia buffs… the guys that do  Ham radio. There are still a few around… but not many.

@wesheadley … “Vinyl records will not vanish along with the boomers. ”.

Well, no, vinyl will not vanish in the next ten years or so… but it will drop dramatically in twenty and be I tiny notch in thirty.

@wesheadley… “Will all wine be in screw-cap bottles in 20-30 years?”

You know… good question. Yes. I have a wine cellar with a few hundred bottles of red wine. I am seeing better wine having screw caps. At first I was very skeptical… the long tradition… the ability of oxygen to slowly age the wine.  The technology to construct a cork. But the amount of tannins in good quality wine has been coming down over the years so that wine sold today is to be consumed in the next few years as opposed to cellared for a decade or two. I don’t see that trend ending. More and more I see real corks only used in top tier wines for connoisseurs.
