" though probably not disappear entirely as the womb thing does still remain."

The implication that gender, family, and children begin and end with mechanical differences like 'womb' is really reductionist. That we are trying to make things fairer for people is a good thing, but it's become so dogmatic we can't consider other ways of looking at it ... is bad.

My prediction is that in 500 years, no matter what we do, we will still see quite substantial gender differentiation, particularly with respect to early childhood.
