Well, if we look at worldwide demographic changes -- both fertility rates and immigration rates -- what stands out is that (1) Africans are having the most children by a wide margin, their total fertility rate (TFR) is above 6 and not coming down very fast because their average IQs are 65-80 and they don't like to use birth control or think ahead, and they live off endless foreign aid, and (2) Muslims, especially Muslims in western countries, have fertility rates consistently at least 1+ children above that of white Christians.
What this mean if current trends continue is that the future is going to be much browner, much blacker, and much more Islamic, as well as much lower average IQ. Because there is a baseline of IQ necessary to keep technological civilization functioning, what we will eventually see is a collapse of technological civilization, much like we are seeing in South Africa today. Indeed, the projected future 100+ years from now is likely going to be black Muslims sitting around their 7th century mud huts telling stories around the campfire of the mythological whites who came down as Angels, bestowed forgotten technology onto the world much like Atlantis, and then disappeared into the nether.
