I enjoyed this read and agree Lenat was a grifter, which is easy to see based on contracts and closed source. But I dislike how the article seems tilted towards a hit piece against search, heuristics, reasoning, symbolic approaches in AI, and even striving for explainable/understandable systems. It's a subtext throughout, so perhaps I'm misinterpreting it.. but the neats vs the scruffies thing is just not really productive, and there seems to be no real reason for the "either/or" mentality.

To put some of this into starker contrast.. 40 years, 200 million dollars, and broken promises is the cost burned on something besides ML? Wait isn't the current approach burning that kind of cash in a weekend, and aren't we proudly backdating deep-learning to ~1960 every time someone calls it "new"? Is a huge volume of inscrutable weights, with unknown sources, generated at huge costs, really "better" than closed-source in terms of transparency? Are we not very busy building agents and critics very much like Minky's society of mind while we shake our heads and say he was wrong?

This write-up also appears to me as if it were kind of punching down. A "hostile assessment" in an "obituary" is certainly easy in hindsight, especially if business is booming in your (currently very popular) neighborhood. If you didn't want to punch down, if you really want to go on record as saying logic/search are completely dead-ended and AGI won't ever touch the stuff.. it would probably look more like critiquing symbolica.ai, saying that nothing like scallop-lang / pyreason will ever find any use-cases, etc.

> 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.

I'd say that being a believer doesn't necessarily conflict with being a grifter. In fact the true believer is practically obligated to engage in tricks, because the ends justify the means. For example taking government contracts for anti terrorism because the problem isn't well defined, your results are hard to check, and the money is going to be good if temporary. Anything where you don't really expect to provide promised value is always worth it because you're going to "pay it back" with big results later. For more recent stuff along the same lines, colonizing mars and getting away from oil are like that too, because for the true believer stuff like this is worth a little stock manipulation or whatever else is required.

Grifting suggests a level of cynicism, that one knows that one is selling snake oil.

I don’t know Lenat and don’t have an opinion one way or another. But be careful suggesting someone is grifting verses just believing in an idea that ultimately doesn’t come to fruition.
