Microsoft's artificial intelligence 'chatbot' messes up again on Twitter

The incident marks another embarrassing setback for the software company as it tries to get ahead of Alphabet Inc's Google, Facebook Inc and other tech firms in the race to create virtual agents that can interact with people and learn from them. The TayTweets (@TayandYou) Twitter handle was made private and the chatbot stopped responding to comments Wednesday morning after it fired off the same tweet to many users. "You are too fast, please take a rest...," tweeted Tay to hundreds of Twitter profiles, according to screen images published by technology news website The Verge. Tay's Twitter account was accidentally turned back on while the company was fixing the problems that came to light last week, Microsoft said on Wednesday. "Tay remains offline while we make adjustments," a Microsoft representative said in an email.
