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

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.
