Sorry, but there is now AI that can beat the best human players at Go, which until recently was thought to be as impossible as beating someone at Civilization. And look how it did it: by playing itself!
AI isn’t hard, it’s just that people are doing it wrong. If a large company like Microsoft would just devote a large team of engineers, a couple hundred million dollars, and several years to have server arms of artificial intelligence play each other in strategy video games, we too could reap the reward of having challenging opponents for Gal Civ or Kingdoms of Amalur. So I’m waiting. Impatiently. With my arms crossed. Tapping my foot with a scowl on my face. A mean scowl. Really mean.
