-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.
+The alignment-theory morals are those of [unforseen maxima](https://arbital.greaterwrong.com/p/unforeseen_maximum) and [edge instantiation](https://arbital.greaterwrong.com/p/edge_instantiation). An AI designed to maximize happiness would kill all humans and tile the galaxy with maximally-efficient happiness-brainware. If this sounds "crazy" to you, that's the problem with anthropomorphism I was telling you about: don't imagine "AI" as an unemotional human, just think about a machine that calculates what actions would result in what outcomes, and does the action that would result in the outcome that maximizes some function. It turns out that picking a function that doesn't kill everyone looks hard. Just tacking on the constaints that you can think of (make the _existing_ humans happy without tampering with their minds) [will tend to produce similar "crazy" outcomes that you didn't think to exclude](https://arbital.greaterwrong.com/p/nearest_unblocked).

+At the time, [I expressed horror](https://www.greaterwrong.com/posts/ctpkTaqTKbmm6uRgC/failed-utopia-4-2/comment/PhiGnX7qKzzgn2aKb) at "Failed Utopia #4-2" in the comments section, because my quasi-religious psychological-sex-differences denialism required that I be horrified. But looking back a dozen years later—[or even four years later](https://www.greaterwrong.com/posts/ctpkTaqTKbmm6uRgC/failed-utopia-4-2/comment/D34jhYBcaoE7DEb8d)—my performative horror was missing the point.

+_The argument makes sense_. Of course, it's important to notice that you'd need an additional [handwave](https://tvtropes.org/pmwiki/pmwiki.php/Main/HandWave) to explain why the AI in the story 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. A faithful antisexist (as I was) might insist that that should be the _only_ moral, as it implies the other [_a fortiori_](https://en.wikipedia.org/wiki/Argumentum_a_fortiori). But if you're trying to _learn about reality_ rather than protect your fixed quasi-religious beliefs, it should be _okay_ for one of the lessons to get a punchy sci-fi short story; it should be _okay_ to think about the hyperplane between two coarse clusters, even while it's simultaneously true that a set of hyperplanes would suffice to [shatter](https://en.wikipedia.org/wiki/Shattered_set) every individual point, without deigning to acknowledge the existence of clusters.
