Here's why Microsoft's teen chatbot turned into a genocidal racist, according to an AI expert

About.me/Azeem AzharAzeem Azhar is the author of a daily AI newsletter. An artificial intelligence (AI) expert has explained what went wrong with Microsoft's new AI chat bot on Wednesday. Microsoft designed "Tay" to respond to users' queries on Twitter with the casual, jokey speech patterns of a stereotypical millennial. But within hours of launching, the'teen girl' AI had turned into a Hitler-loving sex robot, forcing Microsoft to embark on a mass-deleting spree. AI expert Azeem Azhar told Business Insider: "There are a number of precautionary steps they [Microsft] could have taken. It wouldn't have been too hard to create a blacklist of terms; or narrow the scope of replies. They could also have simply manually moderated Tay for the first few days, even if that had meant slower responses."
