"AL still racist and sexist"
Not really, I think. What these results seem to show is that the algorithms are at a very draft stage of development in that they only work well with a subset of the population, and are therefore useless for any meaningful work.
Of course, if they are actively used in ways that directly affect the population then their use is indeed racist or sexist, as appropriate.
I wonder if they are equally bad at recognizing faces across the range of ages that exist - are they also ageist?
