Before revision: Artificial general intelligence Marcus argue that "...hybrid architectures that combine learning and symbol manipulation are necessary for robust intelligence, but not sufficient", and that there are : "...four cognitive prerequisites for building robust artificial intelligence: "hybrid architectures that combine large-scale learning with the representational and computational powers of symbol manipulation, "large-scale knowledge bases—likely leveraging innate frameworks—that incorporate symbolic knowledge along with other forms of knowledge, "reasoning mechanisms capable of leveraging those knowledge bases in tractable ways, and "rich cognitive models that work together with those mechanisms and knowledge bases."
