Too Close To The Edit?
In what I think they said was Phil Spector's first television interview for forty years, the "genius that other geniuses come to" described The Beach Boys' Good Vibrations as an "edit song".
Since he contrasted this with his own composition "Be My Baby" (which Brian Wilson calls the greatest song ever written), I took him to mean that an "edit song" was one that couldn't be faithfully reproduced live and was therefore inferior at some emotional and perhaps musical level. It's an interesting thought.
Perhaps that is what the repulsion of the uncanny valley is about - if something is refined or edited too much, the authenticity is lost and we sense the manufacture involved. This doesn't mean we have to get it right first time, but I wonder if it means we have to know when to stop refining and move to a whole new model/service. Incremental improvements are fine, but eventually they get tiresome. It's easier to be remarkable if you do something completely new.
