I sense a change in the announcer's attitude towards AlphaGo. Yesterday there were a few strange moves from AlphaGo that were called mistakes; today, similar moves were called "interesting".

fun fact: when TD-Gammon hit the backgammon scene in the 90's, it didn't just defeat the top level human pros, it shattered the whole metagame and changed how humans play the game. It could be that human vs human go will look very different in the future due to what AlphaGo has learned and can teach us.

Jeopardy had the same complaints against Deep Blue. The machine was buzzing too fast. Humans knew the answers too but just couldn't buzz in.

Did the machine have a physical switch for buzzing in? Maybe that would've given human a little more advantage

Yup, they built a mechanical 'hand' that they connected to the Jeopardy buzzer

Well, I think the last time computers played the world chess champion (in 2006), they didn't allow the computer to think on the human time! And you can always give the computer less time than the human, but this just shows that it's stronger than you and you need to handicap it to have a chance.

Why wouldn't you allow that? Surely the human thinks in the computer's time.

So that the human has a chance...

Increasing the human time is not an option, since no one wants to watch 8 hour games, and fatigue could also come into play, so the only real option for a winning chance is reducing computer time/power

Human can become tired, emotional and nervous. However, a computer/ software would not have these problems.

Especially for Lee, the whole world is looking at him. An "ordinary" human like me won't be able to make the right decisions under this pressure.

A great respect to Lee and the Developers of AlphaGo. Good Game!

I'm totally uninformed about Go, but by now it seems that unless you're clearly in the lead by the end of the midgame, AlphaGo is going to win, simply because at that point its Monte Carlo Tree Search is going to our-compute you in examining all the tactical variations in the endgame. Lee Sedol really seemed to be under a lot of time pressure at the end.

EDIT: clarified to what I originally meant: "end of midgame"

The thing I find amazing about this is how soon this has happened. We all were expecting this to eventually happen but if you asked anyone who played go and was across the computer go scene when it would happen, say a year ago, they would say it was "10 years out". AlphaGo is one incredible feat of engineering.
