That's not what was said. Current sample rates and bit depths are more than adequate for capturing audio, but that doesn't mean there aren't improvements to be made in digital recording technology. The sound chip on my motherboard and a £1500 audio interface can both record at 44.1 kHz and 16 bit but that doesn't mean they'll produce identical recordings.
Oops that was indeed a slack comment, lol. I only meant the bit depth and sample rate, and assume that over time continual improvements will still be made to the machines/processes.
Another way to ask the question would be whether we might be using 32-bit 384 kHz in 100 years? Except it sounds like there would be no point. I should have said "So it seems the existing digital recording format is more than capable of doing the job, and (production/technology aside) any quality issues are due to format of transmission/playback..."

...that said, few people can hear anything above 15 kHz.
I read/heard something really interesting recently, it might have been here but am not sure - I will check when time permits as it is bugging me now.
The speculation was that people do not merely hear music, they feel it too. In other words music causes vibrations in your body (cavities) which may affect you even though you cannot hear the frequencies responsible. If I remember correctly the specific example I am looking for concern a well-known producer/engineer (?) who had a problem with a certain channel on an expensive desk. At first no one could find the fault, but it turned out to be a high-frequency emission that was annoying the chap even though technically he was unable to hear it. I will watch this video again, although if anyone can find/remember where these comments were, please let me know. I meant to Google it before I forgot the bloke's name!
Anyway, assuming there is something in this, then it occurred to me that we might yet require a higher than expected resolution to cope with inaudible frequencies too?
