Microsoft apologises for AI's 'offensive and hurtful' tweets

Microsoft pulled its chatbot, Tay, just a day after launch. Tech giant Microsoft has apologised for unleashing an artificial intelligence called Tay onto the Twittersphere, after she learned how to tweet abusive, racist comments. "We are deeply sorry for the unintended offensive and hurtful tweets from Tay, which do not represent who we are or what we stand for, nor how we designed Tay," said Peter Lee, corporate vice president of research at Microsoft, in a blog post. "Tay is now offline and we'll look to bring Tay back only when we are confident we can better anticipate malicious intent that conflicts with our principles and values." It didn't take long for Tay to learn the dark ways of the web.
