This is an excellent post, but if I may offer one critique, it would be that it doesn’t answer potential issues of change in population composition. Niklas’ comment mentions this to an extent, but, to be blunt, much of my motivation for worry about population decline and stagnation is a fear of current dysgenic trends, specifically in IQ. The negative correlation between measured IQ and fertility, both within countries and between them, underlies much natalist and transhumanist sentiment.
