This is a nice angle to consider, After non-whites have destroyed european infrastructure they will be exposed to the harsh original elements and force to adapt. In 10,000 years all the mutt descendants of niggers, indians, and whites will look like 100% hyperborean aryans. Even australia will have enough caucasoid dna between whites and indians to maintain itself. Africa is a 50/50 toss depending on how many chinese populate it. If the chinese actually dilute africa then the chinese DNA will be enough maintain civilization. In America, Even American Blacks have an IQ of 85 on average due to white admixture, so even over the next 10,000 years .
Sure, The average South American is retarded, but before europeans came they still manage to build cities and despite the influx of negro genes from brazil, The white DNA can counteract.
Think about it like this, Look at the bright side. The main bane of humanity is nigger and aboriginal DNA and now all that is getting permanently extinguished through race mixing. Even the source of Nigger dna (Africa) is receiving an update from Chinese seed. There's at least a guarantee in 10,000 years that humanity won't have to worry about nigger or australoid genes and the lowest common denominator will be the equivalent of an arab.
