In 2035-2050, noise reduction from power and EMI/RF interferences, as well as non-bass level harmonic room tuning effects and sound staging will be handled by in-ear devices, with automated adjustability of system voicing per album and track, via pre-established user preferences. Dirac will be long dead.
YMMV. Hey, they promised flying cars by 2020 when I was in grade school, so the future is 100% predictable, right?
My crystal ball. With regard to the USA, I'm not sure how alive analogue will be 10 years from now. Alot of folks on this site may no longer be interested due to age. The younger market, who knows. What we do know is that streaming has / is becoming the main preferred source and will continue to grow in popularity / usage as we move forward. I believe the chances are very slim that analogue will be a growth market but maybe you know more than I. And as time goes on, the A v D issue will become more moot due to market dynamics. Perhaps on die hard audiophile sites like WBF, maybe not. But those sites will become less relevant as well.
But I'll say this. There will be a boatload of excellent used vinyl in the not too distant future. On this site alone, could be something in the high five figures. Anecdotally, I'd speculate that numerous WBF members have collections exceeding 10,000 records. Who will buy? The big unknown.
