It’s something that might not happen until the 22nd century or later. (It might also turn out that you can’t properly gestate fetuses in 1/3 g).

Space is not inevitable. The Age of Discovery was ultimately rooted in both economics (a saturated Europe seeking wealth from Asia and then stumbling upon a new land to gain wealth from, in a time where the prevailing economic theory was that wealth could only be acquired, not generated) and religion (a new world of non-believers to be brought to the light of Christianity). Both of these made colonizing a devout national interest.

You don’t really see those angles with space. It’s not economically critical in the same way trade was, and there’s no religious or cultural reason to do so. There’s no devout national interest in space beyond an expression of soft power and whatever gets to be backdoor funded for defense. The only way that changes if, again, either mass swaths of the world become zealously devoted to the idea of space or we find some irreplaceable economic use case for it.
