This is really cool but it's ultimately a stop-gap measure.

Where we want to end up is with artificial wombs because that will ultimately give individuals much more control over their reproduction and will do away with the onerous physiological and psychological stresses that pregnancy puts on women.

Actually we are still discovering and learning about the biology of birthing.

We can now support extremely premature babies outside the womb, but as of now, the risks of growing a baby in an artificial womb is not overcome with the benefits.

Why?

Because you are trivialising the emotions of pregnancy and motherhood. It is not stress all the time, it is also joy and satisfaction and like everything in life, a roller coaster.

I could see this being combined with pigs, to place human embryos in pigs to carry humans to term.

Perhaps there's benefit to pregnancy for both the mother and baby and fully detaching them from the experience might have negative consequences.
