What will become of my beloved CDs?

Now, the first question remaining would be if CD-resolution downloads/streams can actually sound like those CDs. Assuming that new gear does unlock whatever potential CDs have. If downloads/streams equal it, it becomes matter of, more or less, only convenience and then we are back to the original question. What will become of CDs?

elizabeth, 

Your argument about not being able to decode CDs in the future is the same one I use to refuse to go digital in photography - - but to stick to film and photographs printed on archival paper.

Matthew Brady's photographs of the Civil War are still with us, my latest iPhone photo already has been deleted.

Simply nonsense all around...Although actual film is certainly a quaint art form, if you bother to print digital photos they can stick around like any printed film can, and if you utilize safe and redundant storage you can save digital photos instead of losing them to fire, rain, or any of the other losses incurred by most film over the years...research movie film restoration efforts. Elizabeth imagines some less sophisticated future world that can't get CDs to work...science fiction at best and utterly irrelevant to today's world. Downloads and streams allow the rental of music or buying for digital storage, but an actual physical CD can't be deleted, and acts as a permanent physical reference...I can access any of my CDs quickly by sticking one in my CD player.

I concur wolf_garcia
the new gear, spinners included, does indeed unlock our beloved CD/SACD discs for the better.  Happy Listening!

As above,send your un-wanted CD/SACDs to me.   Happy Listening!
