I happen to like what Meizicht has to say. I imagine that someday in the future, gender won't have the relevance it does today, just as today it doesn't have the relevance it did in the past. Meizicht is right that the only real practical reasons to distinguish between gender are sexual/reproductive. And since our species is thriving right now, it's not especially important to procreate anymore. Then, the only reason gender becomes such an important part of our identities is that it has been historically so our society keeps passing that on to its children.
