What's wrong with rule based AI then?

A quick aside.

You may notice that I am not particularly interested in rules based AI.  "Why is that?" I hear you cry.   Well, it serves a perfectly good purpose - it is an engineering feat, essentially, well positioned to fulfill a particular problem solving role.

It is mildly interesting when it is used in a learning context.  And I don't mean when you have to sit through lectures about it, but when you design a system, such as a Learning Classifier System, which can learn rules from experience and apply them in the relevant domain.  But it just doesn't fascinate me in the same way that connectionist, emergent, downright woolly networks which display intelligent behaviours do.  So, when I am obviously looking down my nose at all that is GOFAI, please forgive me - it is entirely my own bias, based on the fact that I don't spend my life looking for solutions to problems, but mainly looking for problems which are begging to be thought about.
