I anticipate (and rather hope for) more differences. The main reason I would hope to see 'gender' differences to cease to be a significant concept is because people will explore whole swathes of new currently unthought of kinds of difference, relationship and community so that simple gender as we know it is lost in the crowd.
Upon reading Eliezer's possible gender dystopias ([catgirls](http://lesswrong.com/lw/xt/interpersonal_entanglement/), and [verthandi](http://lesswrong.com/lw/xu/failed_utopia_42/) and the other LW comments and posts on the subject of future gender relations, I came to a rather different conclusion than the ones I've seen espoused here. After searching around the internet a bit, I discovered that my ideas tend to fall under the general category of "postgenderism", and I am wondering what my fellow LessWrongians think of it.
