Sex differences would come up a couple more times in one of the last Sequences, on "Fun Theory"—speculations on how life could be truly _good_ if the world were superintelligently optimized for human values, in contrast to the cruelty and tragedy of our precarious existence [in a world shaped only by blind evolutionary forces](https://www.lesswrong.com/posts/sYgv4eYH82JEsTD34/beyond-the-reach-of-god).
According to Yudkowsky, one of the ways in which people's thinking about artificial intelligence usually goes wrong is [anthropomorphism](https://www.lesswrong.com/posts/RcZeZt8cPk48xxiQ8/anthropomorphic-optimism)—expecting arbitrary AIs to behave like humans, when really "AI" corresponds to [a much larger space of algorithms](https://www.lesswrong.com/posts/tnWRXkcDi5Tw9rzXw/the-design-space-of-minds-in-general). As a social animal, predicting other humans is one of the things we've evolved to be good at, and the way that works is probably via "empathic inference": [I predict your behavior by imagining what _I_ would do in your situation](https://www.lesswrong.com/posts/Zkzzjg3h7hW5Z36hK/humans-in-funny-suits). Since all humans are very similar, [this appeal-to-black-box](https://www.lesswrong.com/posts/9fpWoXpNv83BAHJdc/the-comedy-of-behaviorism) works pretty well in our lives (though it won't work on AI). And from this empathy, evolution also coughed up the [moral miracle](https://www.lesswrong.com/posts/pGvyqAQw6yqTjpKf4/the-gift-we-give-to-tomorrow) of [_sympathy_, intrinsically caring about what others feel](https://www.lesswrong.com/posts/NLMo5FZWFFq652MNe/sympathetic-minds).
