Garry Kasparov, the world's top-ranked chess player, speaks out on why Deep Junior, the computer program he played to a 3-3 tie a few weeks ago, is a superior accomplishment to IBM's Deep Blue, the computer that beat him six years ago.

In his editorial piece, Kasparov puts forth a compelling vision on the juxtaposition of science and cognition, and touches on the 'why' of the Turing test, instead of just the 'what'.

I just wish the article was expanded to a book. Fascinating stuff.
