You've watched far too many Hinton videos. Cyc belongs to the family of rule-based expert systems. Expert systems were successfully used in medical diagnostics, chemistry, biology and various branches of engineering. Not to mention countless "trivial" applications in planning and logistics for businesses. I could also make a case that DeepBlue was an expert system, and thus add "superhuman performance in chess" to the list. Saying that results from an expert system don't matter (simply because it's an expert system), while believing equivalent results from an ANN will "explode and solve longstanding challenges" (simply because it's "neural") makes no sense. ANNs are not magic.
