The circumstances of that match are still very very shady. Deep Blue prepared for the match using full knowledge of every game Kasparov ever played. Kasparov was not granted access to <i>any</i> game that Deep Blue ever played.
During the match the team kept on reprogramming Deep Blue, to better combat Kasparov's style.<p>Still, these days computer chess programs are probably better than most grand masters. I completely agree that that doesn't say much about AI though.
