Judging by Past Experience…
An attempted counterexample to pro-life reasoning comes from John Allen Paulos:
Let's ask ourselves what position opponents of abortion — say on the Supreme Court or elsewhere — might take if two biological facts about the world were to change. The first assumption we'll make is that for some unknown reason — a strange new virus, a hole in the ozone layer, some food additive or poison — women throughout the world suddenly become pregnant with 10 to 20 fetuses at a time. The second assumption is that advances in neonatal technology make it possible for doctors to easily save some or all of these fetuses a few months after conception, but if they don't intervene at this time all the fetuses will die.The third (unstated) assumption is that technical progress comes to an end.
Judging by past experience with supposedly-intractable overpopulation problems, not long after the above scenario researchers will either find a cure or invent a method of creating basements universes with sharp negative curvatures. (In such universes, exponential growth can be accomodated.) Either assumption is less fantastic than the original.
I noticed, while looking for comments on the above quote, the following from an anonymous commenter at One Good Move:
My right wing friends wouldn't have a problem if the birth rate increased 20 or 30 times. Most of them believe the rapture will occur in their lifetime, so the population explosion would just be a laugh to them.That's close to my opinion. The Singularity (also known as “The Rapture of the Nerds”) is only decades away.
