>Same thing will probably happen to any smaller populations as globalization/interbreeding means massive populations like China/India will end up being the majority of the DNA.

China's 1.0ish fertility rate means that they will be gone in 14 generations or so. India's not that far behind them. It's strange hearing people talk about the "erasure of races"... a meme that goes back 70 or more years at this point, when the only race that will be erased is the human race.

When fertility rates are 1.0, every subsequent human generation is half the size of the previous. Rapid population will become impossible to ignore in just a few decades. Human extinction looms.
