I don’t think that for a person who lives in a world where AI shops routinely sell software that discriminate against minorities, not just in ways that are explained by poorly thought out datasets, saying you’re “so tired” is at all wrong. This is the exact research that Timnit is an expert on, and these are systems that have real world consequences for minorities. It’s easy for people who are not minorities to say you should always a be polite but frankly I think she’s being extremely polite here given all of the circumstances.
