On “Love seems like a high priority”
I thought that Douglas Lenat's remarks (at Lex Fridman's podcast) about this were really insightful1. 1 link to this video

On “Doug Lenat has died”
If anybody wants to hear more about Doug's work and ideas, here is a (fairly long) interview with Doug by Lex Fridman, from last year. link to this video

On “Remembering Doug Lenat (1950–2023) and His Quest to Capture the World with Logic”
There's an interesting (& long!) recent Lex Fridman interview with Doug Lenat here: link to this video Lenat thought CYC and neural nets could be complementary, with neural nets providing right brain/fast thinking capability, and CYC left brain/slow (analytic/reflective) thinking capability. It's odd to see Lenat discuss CYC the way he does - as if 40 years on everything was still going well despite it having dropped off the public radar twenty years ago.

On “Deep Learning's Diminishing Returns”
I do wonder if we'll see the rise of symbolic AI to give deep learning a sense of common sense? I've been thinking a lot about this interview on Cyc: link to this video

On “Remembering Doug Lenat (1950–2023) and His Quest to Capture the World with Logic”
I'll admit it was news to me that Cycorp is still around! There's an interesting thread here that provides some insight from former/current employees into what they are actually doing nowadays. link There's also a lengthy Lex Fridman interview with Doug Lenat, from just a year ago, here: link to this video It seems as if the "common sense expert system" foundation of CYC (the mostly unstated common knowledge behind all human communication) was basically completed, but what has failed to materialize is any higher level comprehensive knowledge base and reasoning system (i.e some form of AGI) based on top of this. It's not clear from the outside whether anyone working at Cycorp still really believes the…
