Will technology make records obsolete one day?

So, IMHO, money will be put to work in developing digital streaming and sound quality will eventually improve to where it is considered the best available.

Exactly. Exactly what was said when the "perfect sound forever" CD came out. And HDCD. And SACD. And probably at least half a dozen in between and since. Which, anybody even remember HDCD? Exactly my point. Obsolete is digitals middle name.

millercarbon, digital (streaming, cd, dvd, sacd, downloads) were 96.4% of music revenues in 2018.  That's a long way from being obsolete. 

My CDs, HDCDs and SACDs still play just fine and not a single digit has been lost to wear, no matter how many times they've been played.  Now I have access to millions of albums through streaming.  How many of the albums released yesterday do you have access to on vinyl?  I can hear just about any of them any time I want.

Don't feel threatened by digital.  If someone enjoys digital it doesn't make your Lps sound any worse.  Enjoy your music any way you want.  That's what it's all about, or at least it should be.
