good news! a human beat AlphaGo1.
bad news! he's an amateur go player2 who works for an AI research think tank, who used a technique that was discovered by another machine learning system which discovered the technique after more than a million games of go.
unfortunately I worry that the future holds a lot of stories like this: a machine learning system deployed on the basis of some thin claim to better-than-human performance, with blatant flaws that lie dormant until some other group of ML researchers have a monetary incentive to prove otherwise.
-
technically he beat a publicly available go player which is considered to be at par with AlphaGo, not AlphaGo itself, because Google doesn't allow people to have access to AlphaGo.
-
the article says he's in the second-highest amateur rank; I assume they mean 2-kyu.
