Consider a problem with scarce resource allocation in a small community with an appointed decision-taker: utility function that intuitively should be used has utility functions of different members of a community taken with some commensurable coefficients.
So you would need some additional structure to meaningfully combine utility functions, but, depending on a scenario, there often are solutions that seem natural in their domain. Of course, if we extend them beyond their natural domain we get all the weirdness explored by scenarios of Dr. Evil running a trillion simulations of himself to foil CEV-performing Friendly AI, and, arguably, SIA vs SSA paradoxes too.
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.
This can generally be broken down to the following claims:
EDIT- Due to some really insightful comments;
I replaced men being prone to aggression as a negative, with men being prone to suicide.
I made the verbiage a little more explicit that no one would be *forced* to change, but would seek out the changes that transhumanism would have available.
