Briefly, I think that Cyc indeed has solved the brittleness problem observed with 1980's style narrow-domain expert systems. During the Halo project, Cyc was merely extended in a principled fashion to answer a battery of word questions in the chemistry domain. In my opinion the chief drawback of the Cycorp approach to commonsense knowledge is their overwhelming emphasis on what Cyc knows, as contrasted with what skills has Cyc learned and can demonstrate. My own work is the construction of a bootstrap English dialog system for the purpose of linguistic knowledge *and* skill acquisition. Also by using a robotics-style hierarchical control system, I hope to later connect high level symbolic concepts with low-level perceptions - as somewhat illustrated by current driverless cars. -Steve

Yes, I'd like to hear others' opinion on Cyc. Personally I don't think it's the perceptual grounding issue -- grounding can be added incrementally later. I think Cyc (the KB) is on the right track, but it doesn't have enough rules.
