#42Some professionals labeled some AlphaGo moves as being unoptimal or slow. In reality, Alpha Go doesn't try to maximize its score, only its probability of winning.
Right, but I think the initial concerns have been proven wrong in some respect. I think AlphaGo can accurately determine when a move in a local area doesn't significantly change the outcome and then just does something else for a different reason. AlphaGo has a higher willingness to go somewhere else, and I think that's the algorithm finding another path that is more helpful than the current one for 1 move.
Humans have a tendancy to want to win the battle, or to get too focus in a local area. I think that's a way AlphaGo is coming up with an extra move here or there which is making a difference in the fight later.

From watching it I'm almost inclined to say it maximizes its chances of not losing over necessarily winning.

#44I guess the next question on my mind is how AlphaGo might fare in a blitz game.

The developers have said that. They also said it doesn't care if it wins by 20 or by 1. It just maximizes winning at all.

#46I wonder what if you put the top 10 players in a room, team up and play with Alpha-Go. They are allowed to make one move within a 1-hour period and they can only play up to 8 hours a day. I wonder what the outcome would be.
Anyway, I think AlphaGo is a great training companion. I think Lee felt he's learning.
Finally, I also feel that while experience is crucial, the older generation would flush out by the younger generation every decade. I wonder if age really play a role in championship - not that AlphaGo isn't considered a 1000 years old "human" given it has played thousands of games already.

#47Earlier quoted context omitted.
As a spectator, I was on the edge of my seat :) As a 3d amateur, I'm really curious about when he resigned. It really seemed like he was playing the position out to go for the win (or perhaps to see how AlphaGo would fare in ko). It didn't look like he was searching for a place to resign.
The AGA commentator (Cho Hyeyeon 9p, at https://www.youtube.com/c/usgoweb/ ) had already been calling the game completely hopeless for Lee Sedol for nearly 2 hours at that point, estimating Lee down by at least 20–30 points before komi, unless by some miracle he could win the ko fight.
Ah, neat, thanks for the link. I didn't look to the AGA channel because I figured there wouldn't be a stream since Myungwan was doing live commentary.

#48Kind of a shame the tournament isn't closer.
As Eliezer Yudkowsky tweeted before the start, the chances were that, whoever won, they'd win by like 4-1 or 5-0. There was no strong reason to expect an even match.

#49It's important to remember that this is an accomplishment of humanity, not a defeat. By constructing this AI, we are simply creating another tool for advancing our state of being. (or something like that)
It is not a tool if you can't control it.
Politicians fool countries delivering empty promises about better health, education and security. A supraintelligent AI could promise making humans rich, healthy and powerful, to then break its promise and dominate the world.

#50The Chinese 9 Dan player Ke Jie basically said the game is lost after around 40 mins or so. He still thinks that he has a 60% chance of winning against AlphaGo (down from 100% on day one). But I doubt Google will bother to go to China and challenge him.
