I am almost certain that by 2100, the current worship of skin-deep diversity will be relegated to the cabinet of ancient curiosities, along with lobotomy, bell-bottom jeans and haruspicy [0], and people will worship something equally weird, but momentarily fashionable.
Diversity is not really a value. If it were, it would have been recognized as such millennia ago, because already the Egyptians and the Babylonians knew what mixed societies looked like. It is not as if American diversity is a new phenomenon, never seen before. Rome or Alexandria in 1 AD was very diverse, and so was India when Buddha was still a young and naive prince.
Real human values, virtues and vices don't change that much across centuries. You can still discern courage, truthfulness, sloth or compassion in stories written three thousand years ago and half a world away. Diversity as a pseudovalue is a modern fad of American origin, partly conjured into being by ancient American racial problems.
Even many American allies (Japan, Taiwan, Poland, Finland, Denmark, Turkey, Argentina, Israel etc.) don't bother to even pretend to worship at that DEI-emblazoned altar, so dear to the good professors of Berkeley. Countries with more distant political systems like the Arab sheikhdoms or China probably don't even understand what the word is supposed to mean.
