Of course ML algorithms can be biased; rather than engaging an Internet layperson who tried to contradict AOC with a silly argument, it would be more interesting if the article engaged the more salient counterpoint to claims like these--attempts to eliminate bias can introduce bias as well.

Anyway, the article is not written in good faith; it's only a step above "BOOM AOC owns Internet conservatives!". There's an interesting conversation in here somewhere, but this article seems designed to avoid it.
