" The space of all possible policies is gigantic..."

Well, maybe not necessarily. It depends on the grain of what qualifies as a "difference", which then classifies policies as unique (individual) or distinct. Also, there are many possible moves in a chess game, but far fewer that make sense.

I found the concrete examples to be a bit dumbed-down compared to the cognitive rhetoric behind the main thrust of the piece. Also of questionable relevance. Contrast was a bit high, too.

Great article!
