That's irrelevant. My point is that no bias is eliminated at first place, since the algorithm is still man made. You could argue that since there is no human intervention the same input would lead to the same output, but again, neither you or I have read the code to claim that it is somehow "bias free" or even completely deterministic, especially if the input relies on computer vision.
