Yudkowski argues that on the scale of intelligence, Einstein and a village idiot are basically right next to each other [1]. So once artificial intelligence gets close to matching the village idiot, it is not far from completely thrashing Einstein.
Now if that same picture held for Go, then a situation like this would seem to be impossible. Either the computer should be much worse than a human player, or much better. It would be an incredible coincidence that, at the end of six months of training, the computer happened to be of comparable skill to humans.
For the game of Go, at least, Yudkowski is wrong. What other aspects of intelligence are this way? Yudkowski's picture seems appealing, but perhaps it is wrong for many areas of intelligence.
