You need to think beyond yourself. You know how to look, how to act, how to eat, how to live. And you have to know that it’s the soul in you, not the external world in you.

 

Go is famous for it’s games between masters and now it seems like machine learning is a new master after playing Lee Sedol in 2016. One of the most famous games is covered in the book by Yasunari Kawabata, “The Master of Go”, it is the historic 1938 match between the reigning master, Honinbo Shusai and Kitani Minoru, referred to as The Meijin’s Retirement Game.
