For a scientist doing a ML system to reconstruct pixelated faces, trained with white faces, why is he/she responsible for "insert larger problem" outside of her/his field?
Do he/she has to also care about the brutal Tantalum Wars because there are some in the electronics they use?
As far as I can see, ML is pretty new, and there is a lot of room for improvement. And I think people need to stop thinking the entire world is racist, or doesn't care or don't want to improve things. Changes take time, and won't happen today, or tomorrow or the next decade.
There is a constant, furious need to point fingers, followed by fear of telling or not telling just the right words on the right order to the right audience. This is not how we are going to solve anything.
