It's funny how some technologies persist for a long time even after they begin to seem antiquated. Another example is phonograph records. It seems strange that not so long ago we used to listen to music played by running a needle through a groove on a piece of vinyl and that this was essentially the same method invented by Edison in the 1870's. These days replacement technologies seem to come along somewhat faster. VHS tapes are headed for obsolescence, but the internal combustion engine is going to be around for a while.

2000 years from now you will still be able to play the LP with a pin stuck in a rolled up paper cone and spinning it. Can the same be said for a CD?
I find that technologies goes in a circle. I mean which came first Semiconductors or vacuum tubes ?

Digital is to analog as a chain is to a string.

Music, melody, is not composed of bits and pieces.
