I don't agree with his take on LLMs. There is something about them that feels very similar to the way my own brain works. Like, for example, when I perceive a smell that, somehow, activates a very old and almost forgotten visual memory. Sometimes, when talking to a LLM, it feels like one or two words in my prompt is having a similar effect on it.
His take may be a bit jaded from his own experience.
He worked as a Lisp hacker at the MIT Artificial Intelligence lab when AI research was peaking in the 1970s.
The commercialization of Lisp and early AI effectively destroyed the hacker paradise he worked in and the following "AI Winter" devastated the research and its funding.
These experiences lead him to start the GNU project, so the net result was good for software, but definitely colored his perspective.
