Is playing go as a team something that people do? It seems unintuitive. I'd expect a team of 5 experts to play worse than one expert.

It is common. The Chinese commentator Gu Li mentioned pair game and team game. But I cannot find an English page about it. Here is a Chinese Wikipedia page. https://zh.m.wikipedia.org/zh-hans/团队围棋 FWIW, the five people team played with Ke Joe before the game and won (again, according to Gu Li.)

Thank you. This is interesting and I didn't expect it!

IMO, you're comparing from the wrong things. AlphaGo is good at playing Go specifically, sure. But AlphaGo was built by machine learning infra that is capable of doing more than just playing Go. Google's ML capabilities as a whole are the 10x developer.

I've once read someone comparing the energy efficeincy of the human brain compared to all the CPUs used by one of these neural networks. The human brain turned out to be more efficient by many orders of magnitude. Sadly I have no recollection of where I've read this.

Sure, but I wasn't making any rigorous statements around human brain power vs Google ML

I was suggesting more simply that the original comment talking about 10x developer wasn't referring to just AlphaGo.

Apparently it wasn't clear that I'm limiting my comments strictly to what's observable in the chat forum and not making sweeping statements about humans.

Though I suspect self-selection bias might also explain the downvotes. Of course everyone on HN is better than a machine, right?

And the brain itself may be. But is the average developer?

My thoughts were on this line also... the same reason the crowd was shocked when Lee Sedol made an unexpected move in game 4. [0]

Is there any research done to prove/disprove that groupthink is inherently worse compared to a single genius? (less risky behavior, so less risk/less reward??) Are we training AIs that will be safe, not bold independent thinkers?

Yes and no. I always said in Pair Go , that 1 bad idea is better than 2 good ones. But provided discussion, you can be a lot more thorough in consensus. Professional analyze and study games in groups, and some thing come out of that. I'd say overall the result is a game with no blunders , but no edge. Since you are sharing the blame of a loss, you are not as focused on winning as you are on not losing.

I think that this is actually an interesting insight into the human condition as a whole.

Not a huge fan of the article but here it is:

I thought this was supposed to be a few years away -- i.e beating Lee Sidol was impressive, but Lee wasn't nearly the top player in the world? Wow, this must be what it feels like to be living on a parabolic curve...

Lee Sedol was near the top (#7). He wasn't the very top, that was Ke Jie. And now Ke Jie has been beaten 2/3, maybe 3/3 times.

Sedol was beaten soundly -- 4/5 games. So this is an improvement, but not an exponential one.

Go is definitely conquered like chess was 1-2 decades ago.

Luckily deep learning computers can directly use electricity produced from sources that don't compete with human nutrition or we'd be in for a very dark future.

You say that now, but then it installs a Dyson sphere. Very dark indeed.

Michael Redmond and Andrew Jackson talked briefly about historical team games while the game was getting underway:

There are other points in the commentary where they discuss some of the team's strategy, as well as their time management.

At this point no one expect alphago would lose. So just have fun

I'd love to take this as far as possible. What happens if you allow the team to roll back decisions as they see they're at a disadvantage? How far away are we from an effectively unbeatable machine? Given what people can learn over time, can they learn to beat it?

There is already a system in Go which allows to measure the difference between unequal opponents - handicap stones.
