Fair enough. I can respect that, and I like your idea, too.
Sounds like the proverbial law of unintended consequences, which would be an interesting twist to the story. Wakanda actively takes part in trying to better the world around it, and by 2099, Wakanda's generosity seems to have (unfortunately) backfired through unwittingly or unintentionally empowering malign individuals, groups, and/or other entities to wreak havoc and inflict harm on the world, forcing the Black Panther of that era to go out into the world and right these wrongs before an all-out world war begins.
