Hot take:
The Compact Disc is still the most futuristic audio format. Forget streaming, files, or the vinyl resurgence, CDs output music at near the top of the quality a human can hear by shooting LASERS at a mirror spinning 8 times per second. This somehow just works and you can read a $0.10 disc with a $20 drive.

When I buy music, I prefer to have it on a CD. I can rip it into my computer easily and if I ever lose that copy I can just rip it again, bit perfect every time. There's no subscription and no DRM that can take it away from me, I have a physical thing.

@artemist
My only counter is that minidiscs use lasers too but like feel even more future-y
@bicebird @artemist I think minidisc uses lossy compression?

@gahms @bicebird @artemist yup - data capacity is less than a quarter of a CD for the same audio length.

Were very useful though, a an early pocketable decent quality audio recorder, I have so many desk gig recordings from mine. I'd sometimes use them in mono for double the time.

The desktop machines were used in broadcast, too, playing out short audio pieces controled from a keyboard, way before PCs could do this...
