"It is our biological imperative to reproduce, but with humanity we can rise above our animal imperatives and impulses."

This is true. However, if the causes for this attitude (biological or cultural) are in some way heritable, we can expect that over several centuries the attitude should disappear, or at least be significantly curtailed. (It is not clear exactly to what extent this is actually the case.)

No opinion is offered on the moral import of these matters. However, any future anthropologists will have something fun to study, surely.
