The topic of leadership today is becoming more interesting than ever.
Personally, I think that continents in general will merge to have one leader. We can see this process taking place in Europe with the UN and "Euro countries" that are uniting together.
Africa will most likely follow the same path in the near future, with having all countries unite to form a sort of collaborated continent having one president, or leader of some sort.
Eventually, this will spread throughout the globe. I think countries will retain their unique cultures. They will be more like states rather than separate countries.
It wonâ€™t be long until we see an African currency. It will come as a solution to the collapse of some African nations, such as Zimbabwe, Congo and so on.
