I don't know if "antiquities" is quite the right word. There's always something to be gained from the existence of the physical format. With albums, for instance, there's the artwork and file quality that you can only achieve with records. (It's why new record players are still being made.) Books can achieve things that ebooks cannot. Same with paintings versus photographs, plays versus movies, DVDs versus digital downloads.

Better to say that the physical medium is no longer the only existing medium. Where they once dominated, now they'll become niche like most mediums do once they're past cutting-edge. But antique suggests something that's over and done with, and incapable of advancing. On the contrary, I think that physical media will continue to innovate.
