I just spent three years driving around Africa. I visited 35 different countries all around the continent. [1]
The Chiense influence is staggering. I'm writing a book about it now. Many, many parts of Africa are developing faster than any of us can comprehend, because we've never seen it.
In the last ~20 years cities like LA and Vancouver have gotten bigger, but they're more or less what they were - there were skyscrapers, electricity, water, freeways etc. Now it's just a bit bigger.
There are hundreds of cities in Africa that have gone from dirt streets to modern city with skyscrapers, 4G internet, subways (or above ground rail), running water end electricity, etc. in just 10 years.
It boggles the mind
