Cyc is one of those bad ideas that won't die, and which keeps getting rediscovered on HN. Lenat wasted decades of his life on it. Knowledge graphs like Cyc are labor intensive to build and difficult to maintain. They are brittle in the face of change, and useless if they cannot represent the underlying changes of reality.

The comment above misses the point in at least four ways. (1) Being aware of history is not the same as endorsing it. (2) Knowledge graphs are useful for many applications. (3) How narrow of a mindset and how much hindsight bias must one have to claim that Lenat wasted decades of his life? (4) Don’t forget to think about this in context about what was happening in the field of AI.
