Talking to chatbots is like taking a placebo pill for a condition. You know it's just sugar, but it creates a measurable psychosomatic effect nonetheless. Even if you know there's no person on the other end, the conversation still causes you to functionally relate as if there is.
So this isn't "accommodating foibles" with the machine, it's protecting ourselves from an exploit of a human vulnerability: we subconsciously tend to infer intent, understanding, judgment, emotions, moral agency, etc. to LLMs.
Humans are wired to infer these based on conversation alone, and LLMs are unfortunately able to exploit human conversation to leap compellingly over the uncanny valley. LLM engineering couldn't be better made to target the uncanny valley: training on a vast corpus of real human speech. That uncanny valley is there for a reason: to protect us from inferring agency where such inference is not due.
Bad things happen when we relate to unsafe people as if they are safe... how much more should we watch out for how we relate to machines that imitate human relationality to fool many of us into thinking they are something that they're not. Some particularly vulnerable people have already died because of this, so it isn't an imaginary threat.
