AI has gone much further than that, and 20 years ago.

Computers are perfectly capable of learning by trial and error to beat humanity hands down. Gerald Tesauro developed a machine that can teach itself to play backgammon.

It does so by playing against itself and exploring policies, not moves, and by punishing/rewarding those policies for how well it is doing. It's called reinforcement learning. The code did not contain any strategies, only the game rules. After thousands of games against itself, it managed to beat average players, Tesauro included.

Then they let it learn from analysed situations from a database (i.e. like from a book) - again nothing coded. After this it could defeat the world's best players and in fact changed the way grandmasters play backgammon.

It's pretty awesome.
