The WSJ article is behind a paywall, the video link works, he's right that the genie is out of the bottle, whether BTC is Napster or BitTorrent in terms of longevity is to be seen.
The video link is terribly slow (less than 0.1Mbit) - dunno why, if anyone could provide transcript or reupload elsewhere it would be greatly appreciated.
As for the Napster / Bittorrent thing, I think we already experienced Napster (Liberty Reserve) so we educated from it and moved on to distributed form now BitTorrent ~ Bitcoin.
