As of my last knowledge update in April 2023, Silvia Killingsworth is a writer and editor known for her contributions to various publications. She has served as the managing editor of The New Yorker, where she worked on both the print magazine and its online content. Killingsworth has also been associated with The Awl, a now-defunct curated opinion and news website. Her editorial work often covers a wide range of topics, including culture, technology, and social issues. Beyond that specific information, further details about her career or biographical background would require up-to-date research or confirmation from current sources.
