I just watched the Cornelia Brunner video, and I disagree with your conclusions, Ben.
First of all, you say "in terms of accuracy of prediction, the femme future won." But those weren't predictions, they were desires. To a certain extent, femmes have recently gotten what they wanted from technology, in the form of cellphones and IM, while butches have not. But it's not that the butches' predictions have turned out wrong; it's that their desires are harder to satisfy, because they are technically more difficult. As I mentioned on Lauren's blog, a jetpack quickly runs up against the laws of physics (assuming that you think a jetpack actually fulfills butch desires).
As for the LHJ predictions, I think many of the ones that came true qualify as butch (aerial war machines, fast trains and ships). There may have been a rise in femme technological advances in the last decade, but when you consider the entire 20th century, many -- perhaps most -- of the technological advances fulfill butch desire.
To use your criterion of whether a technology encourages us to "get very far away from one another" as opposed to bringing us together, I think a prime example is the case of private automobiles winning out over mass transit. That victory wasn't because cars were easier to build, but because people's desire for them was greater. And that example casts a very long shadow: the American landscape of highways filled with single-passenger cars is being recreated by China, the country that may be the biggest player in the 21st century.
Come to think of it, cars are precisely an example of the "bionic," body-transcending technology that (according to Brunner) is the object of butch desire. A friend of mine once said that when she drove a car, she felt like she was transformed into a superhuman being with steel skin and capable of immense speeds. I doubt anyone feels that way riding public transit. Cars are so commonplace now that if you ask butches for their technological desires, they describe something so vastly superior that it borders on the impossible. We have fulfilled butch desire nearly to the limit of physical law.
