As a long-time Go player and ML guy who even built his own (albeit shitty) Go AI in college, I'm a bit biased, but watching the AlphaGo-Lee Sedol match really felt like watching our generation's moon landing.

If y'all haven't already, there's a new AlphaGo documentary made by DeepMind on YT: https://www.youtube.com/watch?v=WXuK6gekU1Y. Brought tears to my eyes. Both a triumph for humanity in building an unbelievable machine like this, and a loss for humanity in that the infinite mystery of Go will be diminished, and again a triumph for humanity in Lee Sedol's brilliant win in Game 4...

FYI Michael Redmond has been doing free commentaries on Alpha Go’s games against itself which are really fun to watch: https://www.youtube.com/playlist?list=PLqpN3-2FP-kIxXhhdDds9...

Really great documentary, can't recommend it enough.

The documentary is excellent. I just wanted to mention that it's from a couple of years ago; it's just only now been put on YouTube.

Q&A after winning game 4:

> What were you thinking when you made that play [move 78]?

> Lee Sedol: Move 78 was the only move I could see. There was no other placement. It was the only option for me, so I put it there.

This is one of the things that bugs me a little in the AI vs Human games. Reading the board is such a difficult skill in GO and humans get fatigued. We have to visually track all the places we could move. It only takes missing one of the top 10 moves on any given turn to lose against Alpha. It would be interesting to have AG or AZ play Lee when he has a day for each move. I'm not saying Alpha wouldn't still win but the computer is so fast and can consider so many things that a human can't hold only in their thoughts.

I do think it is a great achievement how far AI or ML has come. Not to take anything away from the team's accomplishments.

My understanding of high level go is that eventually how good you are comes down to something along the lines of your midichlorian count.

Thank you for this! It was a great piece.
