What needs to be done is to extend the frequency response of CD, not just its dynamic range
as is being done recently. Organizations like AES can start to examine what is needed to
do this, and propose new standards to be introduced

We then would start to see digital really moving forward,
Whilst a turntable cartridge and a phono amplifying stage and its connecting cable, are celebrated as analog
along with reel to reels, in an electronics view a phono stage represents adjusting for correcting what is called RIAA
So an understanding of RIAA
https://en.wikipedia.org/wiki/RIAA_equalization shows that frequency is much higher
in available bandwidth at the cutting lathe - up to 100Khz ( see eRIAA in the above link )

The available bandwidth of LP starts to give meaning to why analog might be preferred when done well.
Those with a LP of Thelma Houston's Pressure Cooker know just what can be done with a analog
direct to disc recording.
