Africanfuturism is similar to “Afrofuturism” in the way that blacks on the continent and in the Black Diaspora are all connected by blood, spirit, history and future. The difference is that Africanfuturism is specifically and more directly rooted in African culture, history, mythology and point-of-view as it then branches into the Black Diaspora, and it does not privilege or center the West. 

Africanfuturism is concerned with visions of the future, is interested in technology, leaves the earth, skews optimistic, is centered on and predominantly written by people of African descent (black people) and it is rooted first and foremost in Africa. It’s less concerned with “what could have been” and more concerned with “what is and can/will be”. It acknowledges, grapples with and carries “what has been”.
