We hear about 20kHz of BW and that contains much less information than the resolution of the eye can use. Such BW could be perfectly digitized with 44.1kHz sampling rate, so we already reached the max at that time, which was not the case for 2D imaging signal. This no magic, this is math. As well 16 bits is a dynamic range if enough to represent our hearing capabilities (assuming you don't want to cover damaging levels). Anybody is free to use 192kHz @ 24 bits and pay for crazy expensive equipment for that, but telling it's much better from a mathematical point of view is just incorrect. You can buy a 20k$ pen if you want, but it will not improve your writing compared to a 1k$ pen. Still you are free to enjoy the 20k$ pen for reasons that has nothing to do with the technology of the pen and the handwriting result, that your money and choices.
