Meta comment: I upvoted this despite disagreeing with a lot of it, because it's an articulate and polite presentation of a view that many HN-ers apparently hold (going by other threads). I adhere to the old norms that downvotes are for non-contributing or impolite comments (like the "you stupid sheeple" form that many others have taken with this), not for disagreement.
