It's still an interesting discussion, even if the possibility exists that it may not bear fruit. The question of the nature of consciousness is one of the deepest unsolved philosophical mysteries that we are still grappling with, but intuition leads us to believe that it must fall to the relentless pursuit of science like all other phenomenon.
I have to agree with critics of functionalism and eliminative materialism that these analyses ignore the central question of consciousness. The problem seems to be such devotion to the scientific paradigm that everything must be explained within a materialistic framework that they are willing to ignore the very data in front of them. In the age old battle of primacy of existence vs. primacy of consciousness, existence seems to have won, at least for scientists, and I personally think they are right. However, scientists tend to want to ignore the fact that the scientific method is an objective epistemic tool designed to study phenomenon that are ontologically objective. That's been great for studying almost every phenomenon known to man, because other than consciousness, all phenomenon have appeared to be ontologically objective. The logical result of trying to impose that framework onto subjective phenomenon is functionalism, a version of behaviorism on steroids. The solution is to basically ignore the subjective phenomenon and explain what EVERYONE can see: The output, or actions of a conscious individual. That may be good cognitive science, but appears to me to be bad philosophy.
