I also feel it's great and useful that Lenat and crew tried so hard. There is no doubt that a ton of work went into cyc. It was a serious, well funded, long term project and competent people put effort in making it work. And there are some descriptions of how they went about it. And opencyc was released.

But some projects - or at least the breakthroughs they produce - are highly published as papers, which can be studied by outsiders. And that is not the case of cyc. There are some reports and papers but really not many that I have found. And so it's not clear how solid or generalizable it is as a data point.
