Hmm... and I know it's possible to get placental tissue to bind with, and grow upon a 'mat' of cartilaginous fibre seeded with uterine cells and supplied with an artificial vascular network, because it's been done back in the 80's. [that research never went anywhere though, no way to support a foetus until now.]

Now, combine the two...

That's just engineering though, the artificial placenta can be grown off to one side, along one wall of the bio-bag aka artificial womb, allowing access from the other side. Personally, I'd build a hard shell, or semi-stiff silicon rubber shell around the inner artificial womb. Give the foetus some room to float around in.

I saw that, but it's a pumpless system because it's open circulation with the foetus. [plus, prior attempts suffered from pressure spikes produced by the pump]. If the foetus has a blood circulation system with a placenta, then the fluid system can run at less O2 tension, allowing a pumpless system with larger volume.

Basically, you can get away with a bigger volume if you use two pumpless systems in effect, one supplying oxygenated blood directly to the foetus's system. I.e copying nature.

You know, one advantage of this tech... no antigens. Which means if you're developing a new species or resurrecting an old one, there's no problem with finding a compatible surrogate womb, and of course, you can design a womb that fits the foetus, so birthing wouldn't be problem.

Point! Not to mention it'd make abortion rather unnecessary.

Thing is, this does make possible a whole range of things that couldn't be done before because the foetus just wouldn't be compatible with *any* mother's biology.

Technically, you wouldn't even need a sperm sample to create life. Just a sample of live cells from a donor. It's entirely possible to create artificial sperm... and unless you specifically want a male offspring it needn't even be a male donor. Heck, maybe not even then if you can obtain a male sample of DNA and isolate the Y chromosome to produce a hybrid genome.

I'd imagine celebrities would have to be rather more careful of their DNA.

You are right though, there is an increased risk of involuntary procreation for men as a result, and it doesn't make the baby go away. Still, sauce and geese you know.

You know, there is obverse too, it makes possible treatments for the mother that would carry too much risk for the foetus. Heck, a women could 'bank' some frozen fertilised ova early on in life, to use later on with an artificial womb avoiding the risks with late life pregnancies. Thus delaying having children.

When I heard about this, the first things I thought were:

-This may make the pro-life lobbies even more frustrating to deal with
-We are one step closer to that Brave New World scenario

If the process does get designed to handle younger and younger subjects, then I can see this working in tandem with CRISPR advances in the following years as well. Not here though, but definitely within countries that have less of the morality obligations to fixate on.

Lyria would be pleased, if she lived in our world. But she's already invented artificial wombs in her world. What's a mad scientist (even in a world of magic) without the ability to create life in a jar? :)

I've seen variations on this theme in many settings, both magical and scientific. That's one reason I keep an eye on such news here.

Yeah, Lyria has always felt the process of pregnancy to be needlessly dangerous, and if the Creator Goddess wasn't known for a fact to exist in her world, she'd consider human pregnancy to be proof that there is no god, because it makes no sense.

On a related note, have you heard of The Long Earth series? It's where humans figure out how to travel one way or another down a chain of alternate earths, most of which are full of life but empty of humanity. Except there are species wandering the long earth that are related to humans, because they figured out how to jump between universes earlier than we did.

One of these other hominids, who were called elves (but more closely resembled grey aliens with fur and sharp teeth) had heads so big they literally couldn't give birth the way we do, so instead the baby jumps from one universe to another. Or is it the mother jumping without the baby? One of those things.
