Gu Li, as quoted by Hassabis, was a lot more philosophical about his loss to the new version of AlphaGo: « Together, humans and AI will soon uncover the deeper mysteries of Go. » Gu Li is referring to the fact that AlphaGo plays Go quite differently from humans, placing stones that completely confound human players at first—but upon further analysis these strategies become a « divine move. » While there’s almost no chance that a human will ever beat AlphaGo again, human players can still learn a lot about the game itself by watching the AI play.
