A story on NPR talks about a new internet worm that is luring AOL users into clicking on a link that allows the virus to spread by chatting with them. It seems that the program is such a good chatter that some people can't tell the difference between the piece of software and their real live friends. It sounds like it passes the Turing test... at least for AOL users.
