kkleiner writes "One of the exciting ideas being tossed around recently at the X Prize Foundation is the creation of an Artificial Intelligence physician that you could access from your smartphone. Want to know if that rash on your leg is poison ivy or smallpox? Take a photo of it with your phone and ask the AI. The possibilities are enormous, especially for the billion plus people around the world who live more than a few hours' walk or drive from the nearest doctor." This is one of four X Prizes in planning for the future. The other three are for an AI automobile driver, organ generation through stem cell use, and a deep sea submersible capable of exploring the sea floor.
