10 years later, what did Kasparov vs. Deep Blue mean?

I found this Article interesting. Exploring the similarities and differences between the "silicon" machine and the "protien" machine and how it makes complex decisions based on precalculated odds, and its own search patterns.

The fact is that the search space for chess is too big for even Deep Blue to explore exhaustively in real time, so like Kasparov, it prunes its search trees by taking calculated risks, and like Kasparov, it often gets these risks precalculated. Both the man and the computer presumably do massive amounts of "brute force" computation on their very different architectures.
