I always think it's strange when people say something is obsolete - when it still works just fine! Or, there is a wonderful, aesthetic reason for using it. How can an artistic medium be obsolete?
Growing up I was very interested in analog music synthesizers, which at the time (the mid 90's, and the midwest) were considered obsolete. Some people would listen to my tapes with a sympathetic ear, but could only allow themselves to hear it in a retro or quaint context. I always wondered why the technology of guitars was able to be frozen in time at it's best, but synthesizers always had to be progressing. I think, in the dominion of synthesizers, the voltage controlled oscillator is akin to guitar strings. You would never get rid of guitar strings in favor of new technology, that would be absurd.
Well, it seems the rest of the world has come around to my thinking in regards to analog synthesizers (I'm way ahead of my time). But the visual equivalent, CRT video, is still banished to the land of the obsolete. Film = piano strings (it's so classic bring it back!), CRT video = analog synthesizers (it's not hi-def enough! get rid of it!), digital = digital (the end of all things). We'll just have to wait and see what happens.
