That sounds like that need to have super higher GMO technology to do that. And also, Besides how do we achieve this… how you describe it, sounds like they will just randomly eat human DNA, Then they lay eggs which hatch into human babies，and then drop the babies off at random houses randomly…..

Which this is some problem… because not like everyone want to have baby or prepared to have baby. and since how you describe it, they seem to be just randomly do this without any plan… so no matter who they good parent or not, have ability to take care of the baby, who are they, are they a family, or even have appropriate age to become a parent.

You can have a situation like a couple that never plan to have babies now have baby, a family that was abuse have a baby, a family that cannot support to take care of a baby have a baby, a man that don’t know how to take care of baby have baby, even a kid… a KID that doesn’t have the appropriate age to have a family have a baby or even take care himself…. Have a baby.

Everyone will have a possibility to get a random baby which including those who don’t want one, who didn’t prepare, who cannot care the baby, who wasn’t a good one to take care of the baby.

That wasn’t a good thing for who ever got the baby and the baby, It will have stress, overwhelming on whoever get the baby because it was so suddenly responsibility, for who did not prepare or want one or not a good one won’t take care of the baby too well, and they might abandoned the baby. All of that might cause much more kid was not to good growing up…..

And also, it sounds like it just needs one DNA then 2 different DNA, which mean the baby basically is a completely clone of whoever it ate….. Which it can have some problem….. Even if It used 2 different DNA to make a baby that wasn’t clone… they still some problem… just another kind…. Like imagine you are going your day until you have a random baby… which is biologically your, and the other person… which both of you NEVER EVER met before, never even face-to-face, so not even body-to-body but now you just have a baby with this random stranger that you never met before….

it will be awkward… and bad, embarrassment or disgusting if you don’t like that guy… In much worse CASES….. Since it doesn’t seem to care what DNA it take, so if might accidentally take two close relative or even siblings, This leads to inbreeding without physical contact…..

Which will have bad affect for the baby And it will cause disgusted and chaos in the family.

So yeah….

If you somehow make this And Place it to the world…. It will cause chaos and people will not be happy about it at all……

You need to fix those problem first if you want to put those to work.
