Ke Jie, supposedly the best player in the world, wrote:
“After humanity spent thousands of years improving our tactics, computers tell us that humans are completely wrong. I would go as far as to say not a single human has touched the edge of the truth of Go.”

In a more positive way (?), great old champion Nieh Wei Ping: “Go is not as simple as we thought, there’s still huge room for we humans to explore. (...) Master is sent by the ‘Go God’ to guide humans.”

PS: personally, I am now curious to see how many handicap stones will need an human to beat "Master"
(BTW, Otake once said: "Playing God, I think I would probably have a good chance playing with 3 stones handicap, but if I had to stake my life on it, I would probably take 4 stones.").
