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???

As above,

the physical format is not going away anytime soon. The players/spinners will be around a very long time as well.  Happy Listening!

I agree with jafant. CD players will be around for a long time. Maybe like turntables these days. Irrelevant in bigger picture, but with enough of die-hard support to make them profitable in those low numbers. Something like 78s. Some turntables can still play them, but it is a very small group of people who may actually use it. And, when nobody is watching, I ask myself why would they use it anyway.
Eventually the codec to 'decode' CDs will be lost to history. It might be near impossible for some future civilization to ever actually decode a CD contents without the knowledge of how it was created. Reverse engineering a CD contents with no idea how (or what is on the disc) may be impossible. The encoding is incredibly complicated, and not in any way conceivable straight forward. So in some future hundreds of thousands of years from now. all those archeological silver disc finds may be an utter mystery to those future beings. Oddly... an LP could easily be decoded..
