I ran into a discussion on Kialo, to which I quickly contributed the first paragraph below and penned what I have added below, all within about five minutes. I later edited it a bit, to make it easier to read.

I am so pleased someone started this discussion. I promote non-discrimination of embryos and fetuses. A child is not a consumer product but a human being who must be loved and encouraged to flourish. How can you love one child but not another if the latter is non-mainstream? I’ve been thinking about that and it’s made me wonder if it actually means that the parents aren’t fit to be parents. I haven’t dared say that out loud yet, but this discussion clears the road for me.

So yes, maybe parents-to-be should require vetting.

Within a few decades, we will no longer require sex to create babies, but will make our offspring in the lab, possibly on the basis of skin cells from each of the parents. We’ll probably look after our little gestating (incubating) children as if they are rare orchids that we want to bring to bloom.

(So by that time, women will no longer have a need for abortions and they won’t have to menstruate and experience PMS any longer either.)

I can imagine very well that you will require a license in the future in order to have a child. Somehow, that feels like an automatic consequence of the possibilities we will have then.

And also, indeed, why should adoptive parents be scrutinized but are natural parents free to do whatever they want?

And after all, in that distant future, anyone who wants can probably have a child (technically speaking). Even adoption may slowly become a thing of the past, that is, if we get to the point that we no longer succumb to illnesses and accidents and maybe even can choose when our lives end.

I hasten to add that at the moment, natural parents are not always free to do as they please either, of course. For example, in countries with a great deal of inequality, the state may step in on the basis of what is no more than prejudice in practice.

Nowadays, some children suffer horribly, either because of their parents or because of someone else. Sometimes before children are removed from their parents and sometimes afterward.

In practice, perhaps it won’t be an actual license but a training program that must be completed with good results. If that training is tough and long enough, that alone will already sort committed parents from parents who aren’t ready for a child.

Would they have to get a license or go through some kind of training program every time they want to have a child? Yes, I think so. Insights change.

It’s even possible that parenting will eventually become a profession.

PS
Unfortunately, Kialo may not work very well with Linux. I was able to post my contribution, but seem unable to comment on other people’s contributions. Maybe it’s part of the learning curve, but I did see the intro video and the comment option mentioned in it simply does not seem to exist for me.
