Suppose the technology you describe is perfected, and we can grow a human embryo in an artificial womb to the point where it can then live on its own. Think how that would affect the abortion debate. A woman goes to doctors and has an unwanted pregnancy ended by having the fetus removed from her body. The doctors now have a living being, separate from its mother, that they can grow and place for adoption later. The mother has no complaint about anything going on in her body, and suffers not further inconvenience. Does there remain any justification for her seeking a “traditional” abortion, one that produces a dead fetus? There are reasons she might want the fetus dead. It bothers her to know the child is out there somewhere, or she may be angry with the father. But these fall far short of a justification for the (now separate) fetus’ death. A real artificial womb would move the date of “viability” all the way back to the beginning.
That date may already be attainable. A decade ago, nearly, I wrote a novel (Evil Interrupted) about the issues and then wrote a non-fiction booklet on stem cells and the goals of research in stem cells. The non-fiction was available online for free to anyone and got downloaded thousands of times. I was hoping We The People would catch up somewhat to the science being done. Apparently, most of we the people have ignored the developments because we’re the creation of the progressives’ media scum.
