Afrofuturism has existed in occasional works for a long time—but in modern science fiction it has turned into a ridiculous mantra.
I think we all have a pretty good idea what the future of Africa looks like—and it will not be pretty.
btw I am currently reading one of the classics:

The book is available online here:

It is interesting that the Wikipedia editors have not chosen to attack it and Amazon has not tried to ban it—at some point some leftist professor will make a career out of calling it racist/sexist etc....
I’ve only read a little of Arthur C. Clarke (some background/alternate materials on 2001 and Childhood’s End for school).
In Childhood’s End as I recall, the aliens who come to Earth put white people in charge of some African government because they are the minority there. But by the end of the novel nothing really exists anyhow, I seem to recall the planet transmorphing into some kind of 2001-ish star child (or star children). I think that the aliens also could show a window to the past to people and it was used to “expose” the life of Christ as “false”.
Then again I don’t know who could hold up Arthur C. Clarke as a paragon of virtue since he’s been accused of being a globetrotting sex tourist/pederast.
