Unfortunately, I feel that the only ones who will "care" about it "again" are the only ones who care currently. There's a reason people don't have Hi-Fi setups anymore; they're completely unnecessary and a waste of time/money/space when >80% of the population will tell you they can't hear a difference between the EarPods that came with their phone, and a $10,000 top-of-the-line stereo hooked up to $2000 monitors. Anecdote time; friends of mine own(ed) a niche A/V store, their grandparents opened the store in the early '60s and their primary focus was to carry, sell, service, and most importantly demo everything from a $50 loudspeaker to the $10,000+ amp. Back then, every product was completely different from the next. A $50 amp and a $500 amp was like the difference between a CRT TV and a 4K OLED TV, same with speakers. About 25 years ago when their parents took over, it was already becoming evident (mainly with everything going digital) that the difference between a $50 amp and a $500 amp wasn't nearly as pronounced as it was 50 years ago. 5 years ago the business pivoted away from A/V, because nobody is going to spend $500 on an amp or receiver when they can pick up a $30 soundbar at Walmart and get 95% of the quality/experience. I've seen it myself; the family is still a bunch of die-hard audiophiles where money is absolutely not an object when it comes to audio, to the point they built a home theater and spent $30,000 on a custom-built 11.2-channel tube-based Atmos receiver, >$2500 per speaker (that's right, nearly $30,000 in speakers), and around $10,000 for each subwoofer. While most of our friend group will tell you it's unquestionably the greatest sounding thing on the planet, there's still a few who'll put in their dollar-store earbuds, load up a 360p song on YouTube, and tell you completely straight-faced it sounds no different.
