CDs are just shiny punch cards with a fancy reader.
@scottgal CDs are just records with light instead of needles.
@lengau Oh records are so much cooler records are a direct reflection of the vibrations which came from the instruments they were created from. Listening to a vinyl from the 1940s connects you directly to the room it was recorded in :) All the variations in the vinyl were caused (directly) by the air moving in that room 80 years ago!
@scottgal
Somewhere I have some of my grandfather's aluminium records... I should find those...
@lengau Just reminded me of music boxes! These were totally a kind of proto-punch card! Maybe #everythingispunchcards should be #everythingismusicboxes :)

@scottgal
Music boxes are just binary wax cylinders 😜

Oh, and storage disks (hard disk & floppy disk) and tapes are just magnetic punch cards. #DataStorageIsBoringlyFascinating
