The "Vibranium" there is irrelevant, unless one of the powers of Vibranium was making Wakandans spontaneously know the Western Scientific Method and how to jump-start Western Industrial Revolution as they did.
Of course, when that's true, it means that stuff like vibranium or other magic-gadgets, if they not only provide a resource but also somehow "enhance" a people to be able to become better than Europeans, is actually SUPER RACIST but NOT the way you think: it's suggesting that Black People or Native Americans or whoever require an artificial deus ex machina to be enhanced because somehow in their native state they would never be the equal to white men.
So is that what the "stuff" in Black Panther, Tikor or Coyote & Crow do? If so, I think those settings are in some ways more white supremacist than Myfarog.
If not, those settings are obviously racist because they suggest that "we were kings" fantasy that the non-white race in question is actually vastly better mentally and ethically than Europeans and would have created a near Utopia of Supertechnology and Social Justice if the Evil White Man hadn't come along and ruined it just as it was no doubt about to start happening.
So regardless of what the explanation is, you judge it to be racist. If vibranium enabled the Wakandan advances, then it's racist against blacks because clearly blacks shouldn't need enhancements to equal whites. If vibranium *doesn't* enable advances, then it's racist against white people because it says that blacks are naturally better than whites. I tend to think that you're just seeing racism everywhere.
I don't see any sign that Africans or any other peoples are any less genetically intelligent or capable than white people. The evidence of history is that they lacked the circumstances of Europe that enabled greater technological advances. For technology - the key seems to be first the Eurasian exchange, then the Columbian exchange.
The civilizations along the Eurasian band -- the Mediterranean, Middle East, India, and China -- all grew more advanced than other parts of the world, by exchanging crops, domesticated animals, and other discoveries along an East-West axis. It is difficult to use and adapt along a North-South axis because the climate changes so much - making things difficult for Africa and the Americas. For history prior to 1492, it was mostly a toss-up to say which was the most advanced along Eurasia. In 1000 BC, Egypt was the most advanced. In 0AD, Rome was the most advanced. In 500 AD, China was the most advanced. In 1000AD, perhaps Persia was the most advanced. It was only after 1500AD, that Europe unquestionably pulled ahead to be the most advanced technologically. I think it is fair to say that they benefited greatly from the Columbian exchange - i.e. the influx of new ideas, raw materials, plants, and animals from the Americas.
Based on this, I think it is not racist to suggest that a fictional influx of new ideas - like psychic powers or enhanced abilities - would allow a civilization to grow more advanced technologically. I don't think that Wakanda's history is particularly realistic, but it isn't based on an assumed racial superiority or inferiority. The vibranium meteor is portrayed a chance occurrence. If the meteor had hit elsewhere, things would have gone differently.

For the record, yes, vibranium has enabled advances. In Wakanda, after the vibranium-laced meteor fell thousands of years ago, a native plant - the heart-shaped herb - adapted to absorb much of the vibranium that now leeched into the soil. Early peoples discovered that by drinking a concoction of the heart-shaped herb, they gained superpowers - which evolved into the line of Black Panthers. The Black Panthers were not inherently super-smart, but they do have superhuman abilities and super-senses. (There's also sometimes been hints of spiritual effects from it - like T'Challa's out-of-body experience in the movie.)
So if a game setting where DUE TO THE LACK OF JEWS, Aryan Europeans were able to become vastly more advanced and create an ethically superior culture by the 21st century is racist.... How is a setting where DUE TO THE LACK OF WHITE MEN, Native Americans were able to become vastly more advanced and create an ethically superior culture by the 21st not racist?
Please explain the difference.
There is a huge difference between:
1) A game with no fictional premise other than lack of European conquest, which claims that it is a realistic projection that Native America civilizations would develop advanced technology in 700 years.
2) A game where there are superhuman psychic powers, billed as "science fantasy", that has Native America civilizations developing advanced technology in 700 years.
In #1, the game is making a false claim about where Native American civilizations would go. In #2, though, it's just a "what if". I could imagine a series of "what if" games which each had what if there was a fictional source of advancement for different civilizations. i.e. What if India got superhuman powers and technology? What if Australia gained superhuman powers and technology? What if Europe got superhuman powers and technology? These aren't racist, because they aren't saying that the *cause* of the advancement is racial superiority.
