I am a big fan of Bruce, have read all his books (well, actually not true for "Applied Cryptography" which in parts is much above my understanding, but I tried it too) and so far all his writings have been a great inspiration and education to me, but I do not agree with most of the points he makes here. For example, he doesn't seem to get the difference (or that there is a difference at all) between POS and POW and quite a few other misconceptions AFAICS.
Anyway an interesting read to know what the crypto guys (<- cryptographers, batslap not applicable!) think about
BTC, the discussion below the article is the most interesting part IMHO.
