I really hoped that Black Panther (the Marvel movie) was going to be the start of a new era of mainstream Afro-futurist fiction. Such an amazing genre/setting/aesthetic (depending on how it's used) that is so tragically underexplored. I've yet to see that really manifest, although I know there are sort of rumblings at the fringes -- the newest Magic: The Gathering set is explicitly paying homage to African cultures and peoples, for example.
