Yet handles are not shaped like hands. The speakers I use on my computer don't look anything like a mouth, nor does the microphone I use on calls look like a set of ears.
Ultimately I guess this is up to opinion, but in mine, humanizing LLMs is not exactly "conforming to human sensibilities", rather it's trying to pass the LLM as something else to make it more appealing. It is deceitful in this way, and that I completely abhor.
For example, "Please" and "Thank you" come from human sentiment. It's an expression of something underneath, and an LLM using such expressions not only is fake, but makes a mockery of the real thing.
