AlphaGo is not an AI in the sense meant by Yudkowsky, I believe. He speaks more of a recursively self-improving AI, an AI which is capable of upgrading itself to be faster and more intelligent.

In the linked article, Yudkowsky even says "On the right side of the scale, you would find Deep Thought—Douglas Adams's original version, thank you, not the chessplayer." The implication is clear that these programs playing chess/Go are nothing like what he is talking about - general AI.

Or so I assume, from my less-than-complete understanding of Yudkowsky's writings.
