I'm pretty sure humans will not stop playing go at intensely high levels just because a computer can beat them. The analogy to chess is an interesting one, though, not quite as straightforward as it may seem. Chess, when it was first conquered by computers a couple of decades ago, was a triumph of computer vs human, sure, but in such a different way from the way humans play it. Chess is amenable to brute force search in a way that go isn't (though I understand the chess programs really aren't pure brute force), but human chess players don't (as far as I know) really don't play chess in a brute force way, they rely in intuition, experience, and even a bit of gambling and hedging whether their opponent will "see" or "realize" the strategy in time. As a result, the chess programs were winning through a "reasoning" process that was very different from what you experience watching people play the game. Something very different is going on when humans play, which makes it interesting - in that sense you can sort of dismiss the machine as playing a different game, albeit one with the same board, pieces, and rules. Instead, it's a giant calculation that happens to beat the more intuitive approach once you can search and score X positions per second through an entirely alternate approach to the game. This current breakthrough with go sounds different, in that it may mean that computers now play go in a way that is much more similar to the way humans play it (it would be interesting to see if a chess program designed more like the go program would have a huge edge over the brute force search approach). Or, if not the same, perhaps a way that is equally if not more interesting. I'm kind of bummed that I'm out of my depth on this one (I don't know go or chess well enough to really say), but it's an interesting question. |
