Right now, the only system I can imagine as non-racist is closed and all of its elements belong to the same race.
Mathematicians would probably call this a trivial description. Comedians might call it a country club.
That moves the question not to whether we can build a system that isn't racist, but what racist qualities need the most suppression and which ones (where we have to choose) can be ignored.
Keep in mind this discussion has been ongoing for centuries and was simpler (e.g. slave vs. free) in the past than today (health, education, economics, psychology, religion.)
And more variables appear regularly.
That said, could algos help judges make more consistent rulings/sentences? Probably already are.
Judge: I'm gonna throw the book at this defendant!
LAL 9001: I can't let you do that.
