Microsoft apologises after Twitter 'chatbot' turns racist

Microsoft is "deeply sorry" for the racist and sexist Twitter messages generated by the so-called chatbot it launched last week, a company official wrote on Friday, after the artificial intelligence program went on an embarrassing tirade. The bot, known as Tay, was designed to become "smarter" as more users interacted with it. Instead, it quickly learned to parrot a slew of anti-Semitic and other hateful invective that human Twitter users started feeding the program, forcing Microsoft to shut it down on Thursday. Following the setback, Microsoft said in a blog post it would revive Tay only if its engineers could find a way to prevent web users from influencing the chatbot in ways that undermine the company's principles and values. "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," wrote Peter Lee, Microsoft's vice president of research.
