That entire section is one big confused contradiction. The author argues that CYC (Doug Lenat's project to hand-code a gigantic database of logic rules encoding common sense knowledge) "can do deep reasoning" because it can answer this question correctly:
How tall was the president when JFK was born?
Unlike Google and WolframAlpha who can only find the closest association (the elevation of the town were JFK was born). Still, the author says, CYC would never "challenge humanity’s unique rational status, any more than computers that could solve equations did" because it doesn't understand natural language, only logic formulae. And yet, the author seems to be arguing that ChatGPT does understand natural language because... it can answer the same question as CYC; albeit in natural language, unlike CYC.I think the author has confused the ability to return results in natural language with the ability to understand natural language. By that token, ELIZA (mentioned at the start of the article) must have also been able to understand natural language, even if it didn't have CYC's ability for "deep reasoning", just because it could parrot its user's input in natural language.
That doesn't make sense. Understanding is clearly something that needs to happen before utterances are formed. Just looking at the output of a system doesn't tell you anything about the internal workings of the system, that's an error that many people keep making in this entire discussion about "AI"s. Look at the sky: the sun looks like it's turning around the Earth. Well, we know it isn't. What we see on the surface is rarely enough to explain what is going on "inside" (or outside, as the case may be, for the sun).
