Thanks for your post - very specific and informative. I believe that it will not be necessary to cope with the corner cases of discourse for a machine to be regarded as intelligent, and I believe that machines that can cope with those corner cases (if realisable ever) may not be regarded as intelligent (I mean, doing this is not sufficient). I think that in this sense discourse analysis is rather like computer chess - a goal that if attained may seem rather irrelevant to the grander challenge of creating machines that are capable of significant contributions to our culture. I think that we risk attacking the problems that appear to us to be interesting.
