I am an avid (but casual) Go player.
As a child, I was mentored by my dad with the Ways of Go and fell in love with it ever since. Go chess is beautiful because of its complexity hidden in its simplicity. I quote Wikipedia “Despite its relatively simple rules, Go is very complex, even more so than chess.” In fact, a bit of research indicates that the number of possible Go games with different outcomes is on the order of 10^100, more than the total number of atoms in the observable Universe.
The recent Alpha Go phenomena, in particular, by the folks at Deep Mind is a major breakthrough of AI technology.
