Being widely spoken in one particular region (or even a few regions) doesn’t automatically connect to being a global lingua franca. If that was the standard we’d be speaking Hindi or Mandarin here. Francophone Africa is projected to experience a popular boom, but even in the best case scenario (i.e. one where francophone Africa experiences better economic growth than other parts) that’d only make it more widespread in Africa. Globally there’s no way it can compete with the rising utility of Mandarin.





The latter usually follows from the former. Wealthy people buy things, sell things, create things and go to places, all of which requires those on the other end of the deal to be able to talk to them. China is also investing in its global image, and in a few decades they’ll be forced to import immigrants to make up the shortfall in their labor force.
Chinese is also gaining steam in Russia and Africa, though admittedly it’s probably going to be at least a generation before it becomes an actually popular language to learn.
