Re: This needs to stop
Industries are never going to be representative of society as a whole, because different people have different interests and those interest are in a large part driven by their peers during childhood. Girls are simply less likely to be interested in technology than boys, this is their choice and their right. Almost all industries are biased in one way or another.
Facial recognition - and optical recognition of any kind is harder when you have less contrast. If the faces are dark and so is the background it's simply a more difficult problem. If facial recognition was better at recognising dark faces than white ones, then people would be complaining that cctv cameras for detecting crimes were intentionally persecuting blacks.
