The global economy is becoming a place where women are more successful than men, and these economic changes are starting to rapidly affect our culture - what our romantic comedies look like, what our marriages look like, what our dating lives look like, and our new set of superheroes.

I deeply believe that men and women need each other.

NASA projects often have romantic names that link into a long history of exploration and adventure: Atlantis and Discovery, for example.

We can no more create the perfect environment for our children than we can create perfect children.

Hollywood is in somewhat the same position as Las Vegas these days. It went from being the capital of sin to Disneyland, and now it's landed somewhere in between. It tries to keep the sins hidden away and outwardly present itself as a defender of American virtues: justice, individual freedom, and the power of one innocent soul to save the world.

In the US in recent years, around a third of all open management positions have gone to women. My research over the last three years has shown that the trend is going in the same direction at all levels. And by the way, it's not necessarily that the rise of women is causing the end of men - it's more the other way around. An increasing number of men are failing during their education, losing their jobs and then not managing to get back on their feet, so women have had to step in. The driving force here isn't feminist conviction, it's economic necessity.

Evolutionary psychology tells us that men, especially powerful men, feel invincible and entitled to spread their seed, and that women can't resist the scent of masculine power. Women, by contrast, are said to be more altruistic and collaborative, seeking power so that they can share it with others.
