My original comment (roughly "there's no intelligence in this article, nor sentience in LLMs") is in response to the blog post's buried lede (that the cumulative activity of LLMs has accrued to a weight of "AGI is around the corner" or "there is artificial consciousness in this matrix").
To be clear, I'm not saying LLMs are useless or a wrong direction in development of "AI," but rather it's the Fool's Gold for the path towards AGI, the pursuit of the academic field of Artificial Intelligence research. A research that I've been abreast of for years before this new age of language models that has made everyone with a keyboard an arm chair expert.
Also, thank you for the book recommendation, it's on my list! :)
So I still disagree with your elucidated point (as you end with "which is valid"): the OP author is using prior art fiction to bolster their opinion of LLM-based software tools as being a possible vector of sentience, not to disarm our chauvinism like the original author intended. If OP wanted to make that point, they could have written a critical essay instead of farming out their thoughts as tokens.
But still, I look forward to reading the book you suggested to understand and appreciate your perspective more.
