There were stories during the expert systems episode in the 80's that some experts when debriefed in an attempt to identify their rules went on to lose faith in their own expertise and to resign from the field. Other anecdotes talked about how some experts weren't capable of expressing their expertise - such knowledge, skills & experience was referred to as 'compiled knowledge', accessible but not expressible, much like Artificial Neural Networks are. Work to address this problem has been underway since the 90's. Perhaps others here can provide an update?

I think a deep neural network trained from self play has a subjective, and even inscrutable inner representation.  Imagine such techniques were applied to public policy decisions or medical diagnosis.   Without a linguistic component that co-evolved to describe a taken action, one could be left with robot savants that outperformed humans on crucial tasks and no one, including the robot, would have any idea why.

I've been watching parts of the match between Lee Sedol and Alpha Go on the youtube deepmind channel.  It's quite good, they start off with a discussion of the previous game, give running commentary during the game, and audibly gasp when the progress of the game shocks them.  The post match press conferences are not to be missed, either.  It's a completely trump free zone.

But you're looking at a full day's work for each game, 6 hours and 17 minutes of video from last night's game which Lee Sedol won.  I was too tired to stay up and watch so I tuned into youtube this morning and watched the endgame.

Apparently I forwarded past the key move, #78, which a Chinese journalist, quoting a Chinese commentator, called "a God's move".  Lee Sedol replied that it was the only move he had at the time, that he had thought it would be easier to make some profit, but it was quite difficult.

So the same play is described as both creative genius and inevitable in the space of a few sentences.  Glad to know that some things will never change.
