Every generation needs to be an incremental step in the evolution to a new species. Other behavioral traits must only be altered when there is no longer a danger from competitive species and our knowledge of our species has progressed to a state of understanding that makes behavioral traits modification beyond question. Until then, we must retain the full spectrum of human variation for the sake of higher adaptability and survivability. Our genders are equal because no more division of labor is required. The mind is the only machine that is really important.
Breeding is no longer the result of sex.
Breeding will be directed by intelligent purposefulness for genetically enhanced children. X. Warfare, that ever present component that drove group evolution to reach Homo Sapiens will continue. Eugenicists will be attacked and we will always be outnumbered. Brains must be used in place of soldiers if we are to hold off attacks and detractors. But war it shall be, even if only intellectual warfare, until we can overcome our own human nature for hostility towards the other and the other is no longer a threat.
