An important point for the people cheering lower population - this is way under replacement level. As previous generations die off and this becomes apparent, the fear is a sudden depopulation enough to disrupt some economies, societies. Picture Detroit, many times over (apologies to Michiganders, since I’ve been to Detroit recently and things are finally looking up after half a century of urban blight) but r pivcture infrastructure like Flint, MI water system many time over. Unstable economies and societies are bad for us all

Given that the article is posted on a science site, and people are discussing this on fairly new technology, I also want to point out that science, technology, innovation are all “luxuries” of an expanding population. As we depopulate and an increasing share of resources go toward elderly care, infrastructure, etc, that’s less for science, technology, innovation.
