We have interesting ways and subtext when we talk about people that show our biases. Actually beyond that the entire article isn't anything about asking Katie questions or how she came about her algorithm. It's more about her fast rising popularity. It's an article that says a woman did something without saying that. I'm not judging if that's offensive or merely a reflection on how we relay news given our society.
