Comparing Man and Machine?

An anonymous reader asks: "Today Garry Kasparov's last of 4 chess matches with the computer X3D Fritz ended in a draw. The totals of all 4 games leave the two opponents tied 2 to 2, revealing that even though the technology has advanced significantly since Kasparov was beaten by IBM's Deep Blue in 1997, the odds are not always on the side of brute computational power. This leads me to pose the question: is chess really a viable way to test whether man or machine is truly superior? Until AI becomes flexible enough to challenge us in arenas like art and music, what would be a better real-life competition?"
