I think the whole premise says terrible things about Wakanda.
The most advanced country on Earth, with super technology and highly skilled people — and yet they have done NOTHING to help the poor and downtrodden nations of Africa. It’s shocking.
At least the European colonial powers went to Africa and built schools, hospitals, roads and bridges. White Europeans delivered many positive benefits to Africans. The Wakandans? They did nothing!!!
I think that's the basic conflict of the movie. The bad guy wants to share the technology.
