Sub-Saharan Africa is experiencing the most rapid population increase in human history. 7 of the world's Top 10 fastest-growing cities are in Africa.

Top of the list of fastest growing cities is Gwagwalada in Nigeria, a place I'd never heard of. It's in Nigeria's Federal Capital Territory, 45 kilometers southwest of Nigeria's capital city, Abuja, and its growth is related to that proximity.

China and Africa are becoming ever more closely bound. China is now the single largest financier of African infrastructure. China is almost every single African country's top trading partner. An estimated 1-2 million Chinese people have moved to Africa. Chinese technology is already shaping the African continent, with solar panels and smartphones leading imports. No doubt Chinese AI & Chinese robotics will be a big part of Africa's future, too.
