"November 2006 match between Deep Fritz and world chess champion Vladimir Kramnik, the program ran on a personal computer containing two Intel Core 2 Duo CPUs, capable of evaluating only 8 million positions per second, but searching to an average depth of 17 to 18 plies in the middlegame thanks to heuristics"
Deep Fritz, in 2006, was superior to deep blue (from 1996!) and ran in a core duo. 8 million positions per second is already completely out of human reach. Even in chess heuristics was the key step and in Go, more is required. Anyway a potato can evaluate millions of moves while the human is racing against time to check one by one.
I don't even know why people make such a big deal. Its not a fair match, and i don't think its supposed to be. Just don't be fools and swallow the idea that its a battle of "minds" or that Google is actually challenging the man. The computer is not even emulating the human thought process. They know they will win, what is done is to showcase what they are capable of to the general public. But discussing the fairness of a match between a 1202 CPUs computer using cloud computing and a human makes no sense.
Your cellphone can brute force you in a simple arithimetics contest while running youtube, the point is that despite that nobody ever did it with GO before because "the technology just wasn't there yet".You cannot calculate to win at go. Simple calculation is not enough for a human OR computer (at least for now).
