What will become of my beloved CDs?


I have nearly 2000 CDs (DVDA, SACD, etc) and am very fond of them, or at least the music that is on them. However, it seems that music distribution is going to someday soon be totally on-line through downloads (True? When?). So, when most all of the music on my CDs is available in higher-quality on-line downloads (with artwork, I'm sure), what will become of my CDs? Will they be the shiny-silver equivalent to 8-Track tapes? Or, will they become a novelty and collectable? Should I seel them ASAP?? Any economists here???

I get that "analog" film is interesting, and I've had great photographers as friends forever, and a cousin who's sort of famous as a photographer and teacher. I do admire the art form of printing stuff in chemicals, and as Ansel Adams said (something like) "It's all in the printing."
I bought all of the 13,000 LPs I had when everyone else was selling them for pennies. Later when I had to move I tossed 7,000 LPs, mostly Classical. Now I only own 4,500 as I have continued to weed.I calculate the 'replacement' value of my 4,500 LP at $90,000 at today's demand and prices. CDs will become the same in ten to twenty years. The young crowd in twenty years will see their parents using streaming and all that as awful, and will jump on actual solid albums. To the dismay of their parent. LOL
"Will they be the shiny-silver equivalent to 8-Track tapes? "
Yes. 8-track tapes are worthless. I tried to sell mine not long ago and would up giving them to charity.
"Or, will they become a novelty and collectable?" No. See above.

They're just a space-wasting different medium for ones and zeros. Nothing to get nostalgic about.
