Control of reproduction, aging and disease will CHANGE everything.
The old family cycle for humans was based on guaranteed pregnancy between males and females. It was also based on aging and set lifespans.
Today pregnancy can be completely eliminated from the cycle. Today people of any sex can merge their DNA into children. And very very soon people will have the ability to never age and never get disease.
Most of the natural incentives for traditional family will not exist anymore so people will be free to completely explore their world as they see fit.
Change is rough sometimes but it is unstoppable, inevitable and just the way things will be. You can’t force people to adopt an old system that no longer makes sense in a new world
