I wouldn't be surprised if, in a month, Lee Sedol was able to beat AlphaGo in another match. This is what happened in chess. The best computers were able to beat the best humans, until the best humans learned how to play anti-computer chess. This bought them a year or so more, until computers finally dominated for good.

It feels really weird to see someone being showered with congratulations for beating a computer program. What exactly is he being congratulated for? For probably triggering and then capitalizing on a bug in AlphaGo's AI? For showing that human resolve, perseverance and a "fighting spirit" can trump a flawed AI, at least until the AI gets fixed? For giving DeepMind extremely valuable test data that will only accelerat…

Perhaps you'd like a shot at explaining why AI is an "amoral field of study", and why it could "delegitimize everything that currently makes humans unique and extraordinary"? Dolphins are about as intelligent as us, too. Are dolphins amoral? Do they delegitimize Beethoven, Tesla, Gödel, Einstein, and da Vinci?

> Dolphins are about as intelligent as us, too

How are you making this comparison?

Relevant tweets from Demis; Lee Sedol is playing brilliantly! #AlphaGo thought it was doing well, but got confused on move 87. We are in trouble now... Mistake was on move 79, but #AlphaGo only came to that realisation on around move 87 When I say 'thought' and 'realisation' I just mean the output of #AlphaGo value net. It was around 70% at move 79 and then dived on move 87 Lee Sedol wins game 4!!! Congratulations! H…

A quote by Lee Sedol from years ago (might be apocryphal, couldn't find the original source):

Q: We heard there's now an anti-Lee Sedol website in Korea?

A: I don't even have time for my fans. I don't care about haters. ("나를 좋아하는 팬들에게도 신경을 못 쓰는데 그들에겐 당연히 신경 끈다.")

We were discussing the probability that Sedol would win this game. Everyone, including me, bet 90% that no human would ever win again, let alone this specific game: http://predictionbook.com/predictions/177592 I tried to estimate it mathematically. Using a uniform distribution across possible win rates, then updating the probability of different win rates with bayes rule. You can do that with Laplace's law of success…

The argument that AI is either much better or much worse does not apply here. It's not an accident that they chose this point in time to play against Lee Sedol instead of 10 years ago or 10 years in the future. They chose this point in time because they thought that they have a reasonable chance of winning.

Also, he won with white but he will play with black next time, so playing the same sequence of moves can't happen. Additionally, even if the AI didn't incorporate any randomness in the opening (I think it does) it may choose different moves if it gets a different amount of time to think, so Lee Sedol would have to play his moves at exactly the same time as the last game. A couple of seconds deviation only has to lead to a different move in one of the 80 or so moves before the mistake was made to invalidate this strategy.

He made $30k for losing that game, so I don't feel too sorry for him.

The best (like absolute best) football|basketball|baseball players in the world make approximately what per game?

Well, defensive end Olivier Vernon just signed a deal with the New York Giants which will pay him an average annual salary of around 17 million dollars. And there was a huge signing bonus as well.[1]

NFL seasons are 16 regular season games, plus 4 pre-season games. And then there are the playoffs, which a given team might or might not make or advance in.

All told, given that the signing bonus is amortized over all the games he plays, the annual salary, etc., I think it would be fair to say that Vernon will make around a million dollars a game.

Aside: Vernon isn't necessarily "the best" DE in the NFL, but due to market forces and the way things work with the salary cap, free agency rules, etc., the contract he just signed is one of the largest for a defensive player in the league. QB's tend to make even more, but I can't recall a really high profile QB who has signed a big deal recently.

since it's markdown - often you get commentish things that allow limited HTML plus indented code blocks, and people get used to using the latter as the only thing that works everywhere
