Can Big Data actually hurt society? Carl and Richard talk to Cathy O'Neil about her book, Weapons of Math Destruction. Cathy has been deeply involved with machine learning and big data for decades and has a broad view of both the potential and dangers of the technology. The conversation dives into understanding how this technology amplifies bias and how that bias ultimately shapes behavior. The trick is to acknowledge that the bias exists - once you see it, it is possible to overcome its effects. Lots of great thinking from an expert in the space!
