This is my generation's Gary Kasparov vs. Deep Blue. In many ways, it is more significant. Several top commentators were saying how AlphaGo has improved noticeably since October. AlphaGo's victory tonight marks the moment that go is no longer a human dominated contest. It was a very exciting game, incredible level of play. I really enjoyed watching it live with the expert commentary. I recommend the AGA youtube chann…

Yep, terrific commentary by Myungwan Kim 9p on the AGA channel. For the folks who aren't as familiar with the game, how did you find the commentary (for any channel)? What would you be interested in hearing for events like these?

I watched most of the game on the Deepmind Youtube channel. Although I barely know the rules of Go, it was really nice that explained a lot of the strategies, although aside from the basic explanations most of the rest still flew over my head. I was still hooked, though.

However it was infuriating that many times they switched randomly between video feeds, so I couldn't actually see what the commentators were talking about on their board. Once it even got stuck on "Match starts in 0 minutes" for a couple minutes!

We still have Arimaa. It's designed specifically to make it difficult for computers to play. http://arimaa.com/arimaa/

It was designed to be hard to win with the algorithms known to researchers back then. I cannot tell if it has something substantially harder than Go has. High branching factor, deep tree and positions that are hard to evaluate with a simple heuristic are present in Go. Does Arimaa have something else up its sleeve?

I'm truly amazed also, I'm not surprised or shocked. Once I knew that the previous master was beaten, I knew it's just a matter of time to see the #1 player topped. What would be shocking is to find out that a famous writer, musician or scientist is in fact, just an alias for an advanced AI system :) It needs a little trick, because people should be tricked into believing that there's a real person behind the name. O…

Earlier quoted context omitted.

Yet people will still tell that worrying about AI taking over is like worrying about overpopulation on Mars, and that this is a problem at least 50 years out. As hard as writing AI for a problem space like "how to win at Go" is, it's several orders of magnitude easier than creating a general AI with the self-awareness required to see us as a threat.

In other words, it could be created in the next 10 to 20 years. We should be taking steps to outlaw black box algorithms right now but I'm sure we won't.

How do you outlaw black box algorithms? What is a black box algorithm? Should we outlaw all calls to libraries we don't have the complete source code to?

I can't understand the call to regulate a technology when it is decades (much more that 10-20 years) away from possibly existing in a state that we can't even imagine. Add to that legislators with zero technical literacy. That's essentially advocating for shutting down all research into a technology that can improve millions of lives.

I was really expecting Lee Sedol to win here. I'm very excited, and congratulations to the DeepMind team, but I'm a bit sad about the result, as a go player and as a human.

But now every amateur will have access to unlimited play against Lee Sedol-level opponents.

Yea, let me just go home and grab my hundreds of GPUs and CPUs.

Can someone explain why this is more impressive than a computer beating top chess players over a decade ago? I'm not very familiar with Go, and while there were far more squares on a Go board, it seems less sophisticated than chess to me.

Maybe Go has way more moves possible and emergent strategies or something I'm not taking into account.

I watched the commentary that Michael Redmond gave (9-dan-professional) and he didn't point out one obvious mistake that Lee Sedol made the entire match. Just really high quality play by AlphaGo. Really amazing moment to see Lee Sedol resign by putting one of his opponent's stones on the board.

Lee had quite a bit of advantages in the middle then he made one bad mistake and that was it. Deepmind made some smaller mistakes too but not as bad. I am really excited about the Deepmind though. Looking forward to tomorrow's game!

What was the mistake that Lee made?

Just for context, this is the first of a five-game match. Next one tomorrow at the same time! (6am CEST, 8pm PT).

Thank you. The title on HN here didn't imply it was a 5 game series at all, nor did the tweet it linked to.

It's a cool win but despite the way the titles are being presented, this isn't over yet.

What do you mean by sophistication in this context?
