I suppose in the era of Bobby Fischer, chess was proxy for superpower one-upmanship. That's long gone, but Chess as a game is still doing fine and I expect that it will be the same for Go. We still have chess tournaments, super-star grandmasters and circus freaks (people who can play blindfolded against multiple opponents). And, yes, computers can easily smoke all but elite players. Why should Go be different?

Because it is far more complex. But apparently self learning KI has advanced enough. And yes, chess has lost some reputation. And I guess it will be similar with go. I mean there is a University just for go. But learning something where you know you can become the best, is something different, than learning something knowing computers will be allways better than you ... so I guess they are having a hard time right no…

But the new door is opened with the ability to play stronger than human opponents and discover new strategies.

Most people other than the researchers and hackers, really did not understand what AI was capable of doing. The very idea of AI seemed too abstract to comprehend(I consider myself guilty).

But AlphaGo showed us what AI is really capable of doing in an eerie sort of way and I think interest in AI will soon become mainstream which is a good thing for the development of AI.

Now it's at least easier to comprehend the context of all those doomsday warnings about AI destroying humanity which I never took seriously.

Someone somewhere asked why a lot of people in the Go community is taking this in a somewhat hard way, here is my hypothesis: Go, unlike Chess, has deep mytho attached to it. Throughout the history of many Asian countries it's seen as the ultimate abstract strategy game that deeply relies on players' intuition, personality, worldview. The best players are not described as "smart", they are described as "wise". I thin…

Now go read "The Player of Games", by Iain M. Banks, to see that idea taken to extremes.

Just read the book and of course was thinking of it when reading his description of Go

I think an important point was brought up by the Google engineer in the beginning of the game: Humans usually consider moves that put them ahead by a greater margin and base their strategies on that, while computers don't have that bias.

Was that in the official livestream, or is there an interview somewhere, where things like these are discussed?

What is interesting to me is that the computer makes clear mistakes when its on the lead. Since it might find the chances to win equally among different scoring results, it often picks a weaker one. This has a powerful consequence: we have not seen AlphaGo pushed to the limit, he is lowering the distances as if it were playing a teaching game. Lee Sedol I think came to this conclusion, and the only human strategy lef…

I don't see how you can term them as "clear mistakes" when the game is playing at a higher level than any of us meatbags. In this case (according to DeepMind) it's no different to a racing driver backing off the pace in the last few laps if they have a big lead - it's better to guarantee a win than to win by a large margin.

You might be confusing correctness with relevance. You can pass at the last move and lose 1 point, but if your lead is 5, its the same win-result but not the same count-result. Well, that would be a mistake by all accounts, even if AlphaGo made it.

Some of the moves AlphaGo played both in this game and the previous one are very definite mistakes, but they were irrelevant to the difference in the game.

Is this just something you're imagining, or did Google's developers explicitly say, "AlphaGo is beyond our understanding. We have absolutely no idea how it makes its decisions"?

AlphaGo developers don't understand how it works in the same way you wouldn't understand how the program you've written to find prime numbers actually found a big prime number. The sequence of operations is known, but numbers are too big to be comprehended.

I think its more like, real parents dont understand why their children do the bizarre things that they do.

I'd bet they'll probably continue playing. They are not using any special purpose hardware, and they already have the software. However, they won't make it such a big PR focus. (And even if they stop, other people will implement the same ideas.)

Putting on a conspiracy hat for pretend, the whole thing is clearly all a big PR scheme to get Google the brand better name recognition and improve their position in Asian markets.

That's not a conspiracy theory - I think everyone agrees this is as much a publicity stunt as a true test. Unless you're suggesting they bribed Sodol to lose?

As someone who studied AI in college and am a reasonably good amateur player, I have been following the matches between Lee and AlphaGo. AlphaGo plays some unusual moves that go clearly against any classically trained Go players. Moves that simply don't quite fit into the current theories of Go playing, and the world's top players are struggling to explain what's the purpose/strategy behind them. I've been giving it…

Sometimes optimal solutions don't make sense to the human mind because they're not intuitive. For instance, I developed a system that used machine learning and linear solver models to spit out a series of actions to take in response to some events. The actions were to be acted on by humans who were experts in the field. In fact, they were the ones from whom we inferred the relevant initial heuristics. Everyday, I wou…

The only frightening part of your story is the insecurity of the human experts.

I've had this thought watching this play out over the past few months. You have this deeply mystical, zen-like game of ancient China which represents the philosophy of the East and it's pitted against this pure capitalist, cold and calculating (literally) machine.

You can hold out for a few thousand years, but eventually the uncontrollable and amoral technological imperative will catch on and crush you.

It's kind of poetic and sad. It feels like technology will render everything un-sacred eventually.
