The great transformation of the past two centuries—the slow but relentless decline of male supremacy—can be attributed in part to the rise of Enlightenment ideas generally. The liberation of women has advanced alongside the gradual emancipation of serfs, slaves, working people and minorities of every sort.

But the most important factor has been technology, which has made men’s physical strength and martial prowess increasingly obsolete. Male muscle has been replaced to a large extent by machines and robots. Today, women operate fighter jets and attack helicopters, deploying more lethal force than any Roman gladiator or Shogun warrior could dream of.

As women come to hold more power and public authority, will they become just like men? I don’t think so. Show me a male brain, and I will show you a bulging amygdala—the brain’s center of fear and violence—densely dotted with testosterone receptors. Women lack the biological tripwires that lead men to react to small threats with exaggerated violence and to sexual temptation with recklessness.

From a good piece on how women are taking more and more leadership positions in the world, and why that's a good thing. The problem with men is testosterone, which manifests in aggression. That may have been useful in a state of constant hand to hand combat war, but it's counterproductive in modern society. When Ali G asked that feminist, “Which is better, man or woman?” it turns out he was on to something, even as she deflected the question.

I suspect the future ideal for humans to emulate in thought and action is a computer, a machine that is immune from the types of logical mistakes driven by emotion and human biology. That ideal brings its own flaws, including software bugs and a lack of some threshold of compassion which humans value so highly, but when it comes to large-scale optimization of measures like happiness, lives saved, misery avoided, computers are likely far superior to human brains.
