I don't agree at all.  Evaluation in Go is qualitatively much harder,
at least given the existing theoretical framework in which we understand
the game.

In Chess, a piece is either on the board or off the board.  A square
is either covered or uncovered.  A pawn is passed or not.  There are
many such easily computed metrics which are typically used in evaluation.

In go, there are no such metrics.
