But that's not really smarter, though, is it? All the computer does is work through every possible combination of moves resulting from its opponent's move, and chooses the best one according to a rule-set written by... a human.
Computers can process data faster than humans, but where they have to laboriously work through every data item, the human brain can shortcut the process - either through recognising a pattern, using experience, or even from "intuition".
I don't think computers will ever be "smarter" than humans. If true AI is ever achieved - and we need to know a lot more than we do about the brain before computers can become more than just sophisticated adding machines that can mimic some of the characteristics of a human - if true AI is ever achieved, then it will result in something that bears so little resemblance to human intelligence that no comparison will be really possible.
