And there lies the fundamental socially-embedded racism inherent in the idea of 'black'. That somehow, having even a fraction of an ancestral African lineage makes a person 'black' - it taints them, stains them and they are automatically labelled as that part, even though they may be 95% other lineages.
For clarity: Why isn't a person who has even 1/64th of a 'white' heritage automatically termed 'white'? It makes exactly as much sense that way. Yet we choose the other.
It's clear that an AI cannot know about this cultural bias. So how on earth can it map an x-ray to the imaginary idea of 'black'?
