I can see raising a child that is not one's own - because it's enjoyable and fulfilling to have a child. But, wouldn't the creation of 'Super-Anything' Humans be one step closer to the Human hive mind?
This, I believe, points to a 'higher, greater good' which is the species itself. So to answer your question, no: its not strange at all to be perpetuating human DNA in spite of ownership. Its the species which owns you, not the other way around. None of us exist without others.
For a certain period in development, children reject their parents, naturally. But then we often come back (often when we are parents ourselves). But, if our children have large genetic changes from us, artificially done, how will our children look upon us? As pets, perhaps? Or mere caretakers?
An interesting (and scary) thing too, is whether higher intelligence - as measured by these metrics - leads to "colder" humans, who make more rational decisions, such as euthanizing the old and weak, which would then include the parents.
