Because technology has changed, the role of men and women are different. Women and men will be full equals. This is one of the most profound changes in human nature. The nature and role of women has changed. Women now have control over their bodies.
Woman can now earn a living and be independent.
The role of men has changed. Men need to find new models, new heroes to inspire them. The hero who subdued nature, protected and provided for his wife and children may no longer be valid. The male structures of hierarchy, chain of command and pecking order may need to be altered. The muscular male hero who defeats all foes may need to be revised.
