> and agree Lenat was a grifter
I worked at Cycorp for 3.5 years, so I can say:
While I haven't been surprised to see Cyc become more and more clearly a failure, Doug Lenat was no grifter. To the very end, he (alongside a handful of others at the company) was the truest true-believer I've ever known. Cyc was his life's mission, and he never doubted that.
