Changing genetics is not enough, creating the ultimate postgender human requires changing the brain itself. The gendered human brain could be rewired to fit a postgender blueprint.
"but only the blurring and erosion of biological sex, of the gendering of the brain, and of binary social roles by emerging technologies will enable individuals to access all human potentials and experiences regardless of their born sex or assumed gender."
Yes, the technological means to these bizarre ends are being developed. They have been in the works for a long time, and we are now confronted with material like this which illustrates the postgender goals which have fueled research from the very beginning. Transhumanism has taken old postgender ideas and built upon them with the description of far more advanced technologies.
"trans- or post-humans would at least be able to transcend the limitations of biological sex and would eventually be able to transcend the biological altogether into cybernetic or virtual form."
The fact that we already depend highly on virtual worlds, especially in terms of satisfying sexual desires is also mentioned. Virtual sex is touted as being safer, easier, and more customizable than traditional human relationships. The gender binary is slowly eroding as people blend their sexual identity with avatars of a different gender and often a different species. The ultimate revolution in virtual sex would occur when artificial intelligence could simulate the erotic response of a human, making virtual sex indistinguishable from the real thing.
"But the final liberation from dyadic, gendered, heteronormative relationships will likely come about through use of drugs that suppress pair-bonding impulses."
Why would anyone actually put such bold remarks down in writing? Why is the erosion of dualistic gender being sincerely explored by the scientific establishment? Is there a collective subconscious desire to merge the two sexes into one?
