Given the secrecy surrounding Cyc we don't know how close or not they got to something AGI-like. Whatever conclusion you draw will be from very little data.
From a practical standpoint Cycorp seems to have pivoted at least 10 years ago into providing knowledge and inference systems for clients. If customers are willing to pay them then perhaps we can conclude there is value in the technology. But again I'm not aware of any public examples to look at.
