Cyc was a “child” of Doug Lenat, who devoted 40 years to trying to make AI more human. David Reed just blogged about it: “Is Cyc dead, as the obituary here claims? Did Deep Neural Nets kill it? I think they both have been part of a process that is killing AI by focusing only on ‘representation of knowledge. My own view is that the neural net training approach used in all LLMs today is not the way to get ‘intelligence’. Nor is the pure Cyc – style approach. Both focus only on manipulating Representation, and in particular representations amenable to simple computation machines. (neural networks or symbolic logic). Intelligence such as what we see in humans, which I call Cognition, isn’t primarily contained within the skull.” Link
