Doug Lenat: “The bottleneck is software, not hardware…. The limitations of WATSON, Google, SIRI, etc. are ones of breadth of inference, not quantitative performance metrics…. For many years now, dozens of us have been building CYC, a repository for the common sense knowledge and general inferencing strategies…. We are on the verge of a sort of Singularity in the building of CYC: it now knows enough, and can infer enough, to carry on interactive dialogues in English, opening up the possibility of having millions of people helping it to cross that finish line in 2012.”
