I would gladly be one of the last nodes standing; I doubt there is any inadequacy in the amount of people willing to run a node without question. Even if an EMP hit or a global blackout occurred, wouldn't that only be a temporary halt in activity? I don't think this would be the death of Bitcoin, unless I misunderstand something the blocks should just pick back up with extremely low-difficulty once we get power back.

Each time the price of BTC drops, whether it is due to the media or something else has always resulted in an even higher price due to the buying pressure at lower price points beginning a domino effect of demand. I don't see the words of anyone as a possible end to Bitcoin.
