The answer you are looking for may be either 'I have no fucking clue' or 'a bizarre monster that looked like a snake with a full-length mirror for a face ate me and apparently that causes people to land in strange worlds'."
It is way, way, too bright, which is why I put shades over my eyes. And apparently our species have mutually disturbing traits. But it seems pretty nice overall.
I've been considering tracking down the inventor of storks and seeing if they'll take help filling out the ranks. I understand why they'd do it anonymously but they could clearly use a little more servantmaker labor on the project. I'm not best suited to detective work but it might be doable.
Uh, control of where children go could get intensely political very fast. If you control storks and you don't like some city-state or some culture or some ideological minority, bam, suddenly you have dramatically more kids than they do, maybe they don't have any, you don't have to lift another finger, they're out of population in a few decades.
There's too many of them, even if you assume absolute convenience of transport. It would also be a major project to raise them in such a way that you could put them back in my civilization so it didn't collapse, but apparently you'd all be up for that, it's just the numbers that don't work.
Are languages really easy for your species or something, you make that sound really trivial.
