dthomas731 writes to tell us that Computerworld has a brief article on some of DARPA's current projects
. From the article: "Later in the program, Holland says, PAL will be able to 'automatically watch a conversation between two people and, using natural-language processing, figure out what are the tasks they agreed upon.' At that point, perhaps DARPA's PAL could be renamed HAL, for Hearing Assistant That Learns. The original HAL, in the film 2001: A Space Odyssey, tells the astronauts how it knows they're plotting to disconnect it: 'Dave, although you took thorough precautions in the pod against my hearing you, I could see your lips move.'"
