I've said it before, this video demo is one of the very best I've ever seen. https://xiph.org/video/vid2.shtml So well prepared, so well presented, so little that could be removed without ruining it. I aspire to do such good demos but always fall so short.
What about for non-humans? Consider a dog that lives with a musician who plays, for example, trumpet. The musician plays the trumpet at home to practice, and also records his practices to review. A trumpet produces significant acoustic energy out to about 100 KHz [1]. When the musician plays live the dog hears a rich musical instrument. When the musician plays back his recordings, half the frequency range that the do…
What about transhumans? I'm looking forward to my HiFi Cochleatron 9000(tm) when my hearing starts to go. Then I'll be mighty glad we made all these high-res recordings.
What if, this actually becomes possible, but we discover that because we previously couldn't hear these frequencies, our instruments and equipment are HORRIBLY mis-tuned and sound terrible? We may end up having to re-record tons of stuff.
Something something premature optimization. And part of me is glad that the art of hand-making instruments is not yet lost; we might need the originals in the future.
Disclaimer: I say this as a completely naive person when it comes to instruments. The answer to this may be "if it wasn't built to resonate at frequency X, it won't by itself," which would be a good thing.

The good news is that you strip out all of this robot propaganda and still hear the exact same music, simply by encoding at a reasonable rate.
The higher frequencies (hi hats for example) are mushy and sound like they are warbling, and the sound just generally has a lack of depth. What is the explanation for this, or am I just imagining it?
Good points in the article, but it has some flaws. The problem whenever somebody writes about digital audio, is that it is very tempting to hold on to sampling theory (Nyquist limit, etc) and totally discard the problems of implementing an actual Analog-Digital and Digital-Analog chain that works perfectly at 44100Hz sample rate. I agree with the assesment that 16 bit depth is good enough; even 14 bit is good enough…
That is no reason to store or even process your music at higher rates, though.
Kind of a side topic, but does anyone know what's up with Sirius XM satellite radio? Whenever I listen to that in my wife's car, I find the sound quality to be obnoxiously bad, to the point that I choose to listen to plain old FM if I'm driving her car.

Sirius XM might be one of the last to standardize on a reasonable LUFS setting of 12 to 16.
While the extra quality is lost on listeners, from experience I've found that super-HQ source material can change your results (for the better) when fed through distortion/compression/warming effects processors
