I read couple of articles in the series and I still couldn't get what was the point author is trying to make. Reads like, "let me give you 100 arguments why I think this is bad".
Do LLMs lie? Of course not, they are just programs. Do the make mistakes or get the facts wrong? Of course they do, not more often then a human does. So what is the point of that article? Why my future is particularly bad now because of LLMs?
How can you argue they don't lie, as if they have any idea of correct vs wrong? There is no brain there. When statistics overwhelmingly say "yes" is the correct answer to something, it will say "yes" -- completely independent of whether that's the correct answer.
The argument isn't that LLMs are bad because they can hallucinate. Author (clearly) argues that LLM use has negative cognitive effects on their users and on society as a whole. Plus, the technology would wipe out a large, large number of jobs.
