I wish I could see the future so clearly!
I only have guesses, and my guess tells me that audio captured from 10 Zoom H2N's at 48kHz will store more information than audio from a single microphone at 480kHz. Current "state of the art" seems to use fewer channels. An advance in the state of the art in the direction of utilizing more sources seems more than feasible to me.
>Psychoacoustic compression does NOT get us closer to the original performance
I think you have missed my point. An uncompressed source is obviously not going to be better than the lossy-compressed data.
However, we do not live in a world of infinite resources. Given the constraints, compression offers new possibilities.
At the same space/bandwidth, you can have, e.g.:
- uncompressed audio from a single source
- compressed audio from 5x many sources
- compressed audio from 2x sources, plus some other data which affects the perception of the sound (???)
This plays right into your question "Why are we only considering bitrate/frequency?" - we don't. Compression offers more flexibility in making other directions viable.
This is why I believe that codec research is important for advances of the state of the art.

In what area exactly? What research? He is not "steering research", he is educating the less knowledgeable general public. So far, your dismissive attitude can also be applied verbatim to anyone who explains why super-thick-golden-cables from MonstrousCable(tm) are a waste of money.

xiphmont's primary goal appears to be to stop Neil Young from selling 24/192 audio to the general public; that's why he called the page neil-young.html. Sure, few buyers have the ears or equipment to pursue anything beyond the compact disc.
The problem is that many readers of neil-young.html will come away thinking they understand human hearing and digital sampling, when in fact the article is far too sparse on details to understand either; there is no discussion of how sounds are located in 3D space, or of how phase information is recovered. It is amazing that you can completely cover one ear, rub your fingers together behind your head and precisely pinpoint where your fingers are. It is also amazing that "Sampling doesn't affect frequency response or phase" but xiphmont doesn't explain this at all.
And then there's this lovely quote:
"It's true enough that a properly encoded Ogg file (or MP3, or AAC file) will be indistinguishable from the original at a moderate bitrate."
which is provably wrong. I can very reliably pick the uncompressed WAV each try when compared against 320kbps MP3.
My attitude is in support of furthering research in the area of live sound reproduction. As I've said, we are VERY far away right now. It is foolish to believe we understand human musical perception completely today. We cannot even replicate a simple cymbal strike with today's recording and playback technology.
I would encourage the curious to stand in the center of an outdoor arc of 100 horn players, like this (feel free to skip first 48 seconds):
