Yep. I predict that Japan will go first. They have the pressing need for more people, a weird societal refusal to reproduce, the technological ability, and the sheer weirdness of it all will appeal to them.
Russia too. I remember reading that the birthrate was so low that the government was paying couples to have kids.
Again... All those books and movies where meant to be warnings, not instruction manuals.
To what degree is Japan’s problem it’s lack of affordable housing? If they stopped giving farmers so much protection and built a lot more housing, families could get apartments larger than a rabbit hutch and feel comfortable having two kids instead of literally squeezing in one.
