What is "Wakanda"?

Rating: 9/10 (4 May 2018)

The fake African nation of Wakanda is the main setting for the film Black Panther. As the movie is full of riveting action scenes and witty quips, there was a question that had me wondering after the movie. That question being, "What is Wakanda?" Is this fake nation one that remains in a pre-modern mindset, or is it a modern nation? Perhaps it is even post-modern or beyond?
Personally, throughout a bulk of the film I would say Wakanda is a pre-modern nation with incredible technology. It is a nation that focuses tremendously on tradition and relies solely on the decision's of its king. However, at the end of the film something changes.
T'Challa (the Black Panther and king of Wakanda) moves towards making Wakanda a nation that no longer bases itself on past tradition, but rather towards helping those in need. In other words, T'Challa is moving beyond tradition to do what believes is right. Why? Because there is a view of superiority that Wakanda has (and rightfully so) compared to the rest of the world. It seems as if this nation has made the jump to modernity with this change of view from its leadership.
What are your thoughts? Is Wakanda a pre-modern, modern, or post-modern nation? Did the nation change its views at all from the beginning to the end of the film?
