Tangentially, though, I think there's something to the complaints about music. Why does pop music have any noticeably autotuned singers at all, when anyone who regularly goes to karaoke bars knows that there are lots of good singers everywhere? In other words, why is being a good enough singer that one can record an impeccable vocal in one take apparently not a prerequisite for a recording contract?
Edit: To bring this back around to the topic of the article, I think the discussion of autotuned vocals might hint at an answer to the question about individual geniuses: it's not as important for individuals to have extraordinary abilities when technology can help us all do so much. I admit I was being a curmudgeon above; I know that autotune can be used to subtly improve mediocre vocals, in addition to enabling the obviously artificial sound that many of us consider crap.
