Humans never seem to learn that interfering too much with the delicate balance of nature / evolution can lead to terrible outcomes because of unintended consequences.
I'm not saying we should eschew every modern scientific and medical advancement, but caution and humility should not be dirty words.
People think humanity will reach some apex of civilization by inventing the most impressive technology, but I believe humanity will reach its pinnacle only when it learns to responsibly manage the balance between our desire to conquer Nature with our needs that arise from being a part of Nature. This might involve conscious decisions to not pursue certain technologies because they could divorce us from what it is that makes us human in the first place.
Humans are good at solving the technical aspects of issues or undesirable / tedious problems. The efficiency and clever designs of machinery and factory production lines are a marvel, for example.
However, humans are notorious for causing more damage and suffering because of our arrogance and overconfidence about how 'good' we really are at the things we do. Introducing a predator to deal with a pest and then realising it has decimated a whole load of other rare species to the point of extinction is a good example.
The question is not so much about whether babies can be gestated in artificial wombs - I'm sure it is a 'problem' that can be 'solved' given enough time and money.
To me, the bigger question is how has evolution shaped the reproduction of our species and what limits should there be (if any) on our interference with it due to our history of unintended consequences?
You know the explanations around time travel, the grandfather paradox etc and how every action you do in a specific timeline could have ripple effects on other timelines or even affect your own existence in your timeline?
I think there are parallels on a biological and ecological level in that every human interference generates consequences against ourselves and our environment and society. The key is figuring out what consequences we can live with versus ones that we shouldn't.
Contraception, abortion, fertility treatments etc have all had positive as well as negative consequences on our society, but overall, we judge the positives to outweigh the negatives and therefore worth pursuing.
Artificial gestation could bring in positives, but it could also cause some terrible problems or lead to an ethical quandary.
Wombs are not just a sterile sack for zygotes. As the foetus develops it is linked to the outside environment via its mother. Babies hear their mother's heartbeat, her voice, acquire nutrients and immunity via the umbilical cord, hear other voices of family members and sounds etc. There are so many factors that we don't understand or are still learning about in terms of how our bodies and biological mechanisms have evolved.
Also, the physical and biological processes of pregnancy and childbirth is what enables mothers (and by extension fathers as well) to actually bond with their offspring. Yes I know some women struggle due to various issues, but our species has continued because for the vast majority of mothers the bond created with their babies is sufficiently strong enough to ensure the children are protected and well looked after until adulthood. Lots of other species have similar mechanisms, especially mammals. It is gestation and birth that invests parents in the well-being of their progeny.
By severing the physical and biological link between parent and child, it could have serious implications for our ability as a species to successfully continue over time.
