Cd's to make a come back in the future?

If this can happen, why not a CD comeback?

CDs need to fade away before they can stage a comeback.
They are nowhere near the “ extinction “ level that vinyl was at.
I do not see them ever reaching the same state that vinyl did or  indeed ever reaching the same status as vinyl has.

uber makes a great point in that they have never really left us. As far as them ever being really popular again, I think it depends on the advancements that are made with DAC sound quality. That said, there has been notable advancement in that area over the last 5 years or so, it could happen. On the other hand due to streaming, it probably has as much chance as disco or the hula hoop to ever being popular again. Who knows. 

I think the CD _has_ left us.  Except for audiophiles, when was the last time you saw someone use a CD?  Maybe someone driving a car that was 10 or more years old?

I'm 42; when I fell for the audio hobby eight year ago, I dove into digital since 100% of my music collection was CDs.  (Much respect to my vinyl brethren.)  I've since ripped them all to flac on a hard drive.  But streaming from Qobuz and Tidal sounds _better_ than the local flacs.

So I only stream, but I keep the hard drive, and its backups -- okay, and a few hundred CD in the attic -- in case of wartime.

I'd love to see the public realize that CDs sound better than mp3 streams, but those interested in physical media (for its very real virtues) are gonna spin records.

Many new car models are produced without CD players.

Also, the concept of streaming and "on demand" music, especially for the under-27 generation, is an expectation, not a novelty.

That said, whether you stream Tidal or Deezer or Spotify or Quboz or whatever, you're simply renting the music. Once your subscription goes, so does your music. However, with generous data plans and ever-changing playlists and the paucity of album sales, I can't see the album-format ever really making a huge comeback, especially among cd's, and especially amongst a listening public whose appreciation of 320 kbs is just as real as ours is for lossless.
