We can also arrive at Brave New World style human production. Babies are produced in factories according to characteristics projected to be in demand by the time they have fully grown. Except instead of the alpha-beta-epsilon types in the book, we may be able to breed for maximum diversity for maximum potential resistance against diseases. Or, of course, any other objectives, technology permitting.

We may also arrive at a common trope in sci-fi where reproduction is not an individual (or couple) decision. By default, individuals do not reproduce and the factories keep the society populated.
