While I dislike LLMs as much as the next guy, I actually find the use of the term "clankers" to be the opposite of dehumanizing. Admittedly, I think I may be on the more empathetic side, but when I see/hear it used it feels like you are trying to be discriminatory to a race or group of people. I have never considered LLMs or AI to be sentient but that recognition of a pattern triggers an empathy within me that is missing without its use.
