There are a few myths surrounding the black belladonna. It has been considered a magical plant with mind-expanding and cosmetic properties for centuries. Because of its poison it was also used as an instrument of murder, which is believed to have killed Emperor Augustus. In English it is therefore known as deadly nightshade . Researchers at the University of Chicago have now programmed a virtual version of the deadly nightshade plant. Instead of human rulers, you can use it to poison artificial intelligences.
