-At the time, [I expressed horror](https://www.greaterwrong.com/posts/ctpkTaqTKbmm6uRgC/failed-utopia-4-2/comment/PhiGnX7qKzzgn2aKb) at the idea in the comments section, because my quasi-religious psychological-sex-differences denialism required that I be horrified. But looking back eleven years later (my deconversion from my teenage religion being pretty thorough at this point, I think), the _argument makes sense_ (though you need an additional [handwave](https://tvtropes.org/pmwiki/pmwiki.php/Main/HandWave) to explain why the AI doesn't give every _individual_ their separate utopia—if existing women and men aren't optimal partners for each other, so too are individual men not optimal same-sex friends for each other).

+On my reading of the text, it is _significant_ that the AI-synthesized complements for men are given their own name, the _verthandi_ (presumably after [the Norse deity](https://en.wikipedia.org/wiki/Ver%C3%B0andi)), rather than just being referred to as women. The _verthandi_ may _look like_ women, they may be _approximately_ psychologically human, but the _detailed_ psychology of "superintelligently-engineered optimal romantic partner for a human male" is not going to come out of the distribution of actual human females, and judicious exercise of the [tenth virtue of precision](http://yudkowsky.net/rational/virtues/) demands that a _different word_ be coined for this hypothetical science-fictional type of person. Calling the _verthandi_ "women" would be _worse writing_; it would _fail to communicate_ the impact of what has taken place in the story.

+Another post in this vein that had a huge impact on me was ["Changing Emotions"](https://www.lesswrong.com/posts/QZs4vkC7cbyjL9XA9/changing-emotions). As an illustration of how [the hope for radical human enhancement is fraught with](https://www.lesswrong.com/posts/EQkELCGiGQwvrrp3L/growing-up-is-hard) technical difficulties, the Great Teacher sketches a picture of just how difficult an actual male-to-female sex change would be.
