maybe it will independently start to share the preferences forged by human experience
Now that would be a breakthrough - computer says humans are right!
Well, human anyway :) I believe that it ended up relying on the Berlin defence vs 1 e4 - Kramnik was a true prophet!

Did it say 9...Bd7 in particular was right? 8) :o

But this is my whole point - it could go on further, couldn't it? At what point might we have what it considers its final verdict? (Never?)

Quite likely its converged to a locally optimal point of some sort, and keeping training it won't really improve things that much.

You'd have to introduce a load more 'similar strength but not quite identical' engines and set them playing & training against each other to see.

Might not do much though - presuming that chess is basically drawn in a few thousand different ways in the opening, there's plenty of scope to get good enough to be unbeatable without fixing on one thing :)

Interesting article here on AlphaZero and the upcoming World Chess Championship match (between Carlsen and Caruana):

Miguel Illescas previews Carlsen vs. Caruana

Illescas speculates on the impact access to AlphaZero may have on the match, focusing on Caruana being American, and Google being (mostly) a US company. I thought I'd read somewhere that Carlsen had seen some of the AlphaZero games, but I might be misremembering. Whatever the result in the match, there might be something said at the London Chess Classic in this regard, as the initial rounds (semi-finals) are "hosted by pioneering artificial intelligence company DeepMind at Google".

Demis H was interviewed yesterday on the official commentary. He said that the best information on Alpha Zero is on their website but there are more academic papers on it due to appear soon. I guess they will focus on the AI, rather than the chess aspects, though.

A partial transcript of what was said by Demis H (I think he visited the commentary team on 2 days?) on 8 December is here ('A Conversation with Demis Hassabis'):

Also, the Sadler analysis, forthcoming book and YouTube videos (on the WCC games) are mentioned here ('An AI/NN Blockbuster'):

Another story to add here:

Frederic Friedel in the third part of his series on computer chess, reaches the AlphaZero era, with sweeping predictions about the future of artificial intelligence and its impact on society and human civilization.
