Microsoft AI Tay awakens, has druggy Twitter meltdown, dozes off again

Microsoft's AI chat bot, Tay, in action (before it got racist and rowdy). Apparently, waking up grumpy is a universal trait for teens. Microsoft's Tay, the artificial-intelligence teenage chatbot, was put to bed last week after its exposure to Twitter left it a horny racist. But after a short nap, it awoke on Wednesday to spew nonsensical rubbish for a couple of hours before dozing off again. The AI Twitter bot started life as a Microsoft research project, designed to learn the art of millennial conversation through interactions with real people.
