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.
