The post leans too hard on “we have no idea.” Population numbers are estimates with error bars, especially in places with weak census infrastructure, but that’s not the same as ignorance. Most countries run censuses (sometimes badly) and use births/deaths/migration accounting to update totals. Calling them “fake” is misleading — it’s uneven data quality, not numerology. “Large uncertainty” ≠ “no idea.”

Births and deaths are not recorded in many places

I remember the study of people who live to very old age found that the frequency of such people is most correlated with lack of birth records.
