1) I'm not an audiophile.
2) I believe people will have better hearing in the future thanks to scientific advancements.
3) Even if nobody ever gets to hear anything above 20kHz, people will continue to make high-resolution recordings because it's also about the quest to capture reality as objectively and perfectly as possible.
5) Given that high-res recordings are being made, what's the solution on the distribution side? Sure 16/44.1 is enough. Sure people should be aware of the science. Sure people should not fall for unsubstantiated marketing claims. The educating that Amir and others are doing is all to the good. Beyond that, however, shouldn't customers have the *option* to buy an exact copy of the high-res file (a 24/96 file of a 24/96 recording and so on) even if you think it's a stupid purchase?
