There are a few black scientists, engineers, mathematicians that have contributed because the bell curve dictates that within every race there are bound to be a few smart individuals, even if it is to a smaller extent with blacks.
What I’m more concerned about is that the population of Sub-Saharan Africa is projected to reach 4.2 billion people by 2100, which will not only drive the world’s average IQ off the cliff, but contribute catastrophic amounts of greenhouse gas emissions into the atmosphere from their fossil fuel projects building oil and gas pipelines. This in turn will create the biggest refugee crisis we have witnessed in history, more severe than the one from years ago with refugees from North Africa trying to cross the Cyprus Sea, which I predict will cause the emergence of far right parties in North America and Europe.
They will destroy what natural habitats and ecosystems are left remaining in Africa , to make way for deforestation and drive more species to extinction. They have arable land but haven’t taught themselves food production, so most of their food is delivered from imports by wealthier white countries.
@Zhou Chang-Xing wrote that intelligent blacks were dying and having less children, while the low IQ unintelligent ones would be having eight children and could never fathom planning for the future. I do think blacks in particular would benefit from a eugenics program where the means of reproduction is seized by the government and made highly restrictive, so that only the intelligent ones are allowed to reproduce while the unintelligent ones <100 IQ are sterilized and removed from the gene pool.
I predict there will be more civil wars, genocides, diseases, misinformation, and other cataclysmic events being swept under the rug because Africans for the most part are incapable of self governance and already have strained systems.
