Consciousness is a privilege or aspect of a complex social/environmental scene, it is not a core requirement for species survival.
Really not sure about that statement. Lots of very old-school assumptions embedded there. I'd say 'consciousness' is a lot older and deeper than just humans, and long a key to "species survival."
In other news, I appreciate Ralph's point about how the cheapness of digital recording contributed to its dominance. I can remember recording on analog equipment in the 80s, and marveling at the beauty of the playback on a good reel to reel machine (can't remember the make). I don't recall ever having that feeling with digital recording.
But on the other hand, one has to recognize that the cheapness and ease of digital recording and reproduction has led to an incredible amount of musical creativity, whether through digital sampling, listeners 'curating' huge collections of diverse music on their hard drives, or the democratization, to a point, of musical recording. Digital has been detrimental but in the very limited (and elite) value of accurate musical reproduction in the home.
