What is "naturally?" At some point in technological progress, we need to build machines to have children. But go a bit further along the line, and maybe we'd find the human body automatically building the machine that builds the human body—in effect, laying eggs.
Er, sorry, I just meant that as "at some [early] point along the timeline of the possible developments in biomedical technology, the world would look like one where—at least early adopters—would need a machine to make children." I didn't mean to imply that there's some sort of imperative to go toward that point.
