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.
Blindsight is a remarkable book - I hope you enjoy it!
Plainly, based on the current ground trodded and the trajectory laid out by the frontier AI labs, I do not have concrete evidence/proof of sentience having emerged from LLM-based software tools as of June 4 2026 nor do I expect it to happen in the future based on my understanding and observations of this technology. I'm not excluding the possibility but wielding skepticism. I am open to being proven wrong with new discoveries.
Which is why (to return to my lashing of the dead horse) I don't see OP's post as worthwhile. Their post reiterates a point that is already valid (the prior art) with no new substantial discovery. Which is why "unoriginal and pointless" is apt, a novel idea was not presented; it's just some vain virtue signaling.
