On the first Feminian Sandstones we were promised the Fuller Life
(Which started by loving our neighbour and ended by loving his wife)
Till our women had no more children and the men lost reason and faith,
And the Gods of the Copybook Headings said: “The Wages of Sin is Death.”
In CS Lewis’ Space Trilogy, the evil inhabitants of the far side of the moon no longer have sex with each other. Each of the married people has sex with a robot, or something like a robot, and their children are put together in something very like in vitro.
IOW, we’re very nearly there.
