What's the News: Ever since Alan Turing, the father of modern computers, proposed that sufficiently advanced computers could pass as human in a conversation, the classic Turing test
has involved what's essentially instant messaging. Computers designed to imitate human conversational patterns are often entered by their designers in competitions where they aim to fool people in front of a distant monitor into thinking they're human---and they do a pretty good job, although some human mimics, like chatbots, sound like crazed children on their first spin in cyberspace ("I'm not a robot, I'm a unicorn!
