If one pays attention to technology-based news all the big players in facial recognition technology are now refusing to provide this technology to the US government and/or police. When news reports on this the generally imply the new refusals are caused by George Floyd's death and fears of racism associated with the technology, though they never elaborate on the specific fears.
I'm aware of the general concerns about the potential for abuse of facial recognition to lead to a 'Big Brother' police state, but I'm curious about the specific unclear claims about facial recognition being associated with racism; I'm not sure I understand that specific concern.
I'm aware of examples of early facial recognition technologies worked better on Caucasians than other races, but that seemed to be a failure to utilize a properly representative set of photos to train the technology, fixing this specific issue seems to only require an intent to get a more representative training set, it hardly seems an unfixable issue.
Beyond that I would think technology would be less racist than humans; my neural net doesn't have subconscious biases that cause it to make presumptions about an individual based off of the color of their skin, but study after study prove that humans, even those who otherwise do not show any outward sign of racism, are guilty of such biases. So why would facial technology be thought to lead to racist results?
