As u/tj-teej pointed out [0], the utilizers of this tech have the agency and means to improve or mitigate the tech, including prioritizing the training of algorithms to handle black hair styles instead of shunting it off to an edge case, conveniently burdening a demographic who has been historically limited in power and influence.
To think of it another way: in many parts of the U.S., Asians are very much a minority. Asians more commonly have narrower eyes which can interfere with face detection/recognition [1]. In the near and possible future, when face-detection becomes a "feature" in security tech as a means to expedite processing -- e.g. if your face is scanned and not found in a "Real ID" database, you're automatically put in a line for more invasive searching -- would Asian-Americans not have a legitimate case that the U.S. gov't has failed to improve their tech to the detriment of Asian-American citizens? Especially when it seems Asian countries have successfully mitigated the issue?
