Doors aren't humans either, yet we design their handles and locks to be graspable and manipulable by humans.
The purpose of technology is to serve humans. Therefore, technology must conform as much as possible to human sensibilities rather than vice versa.
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.
> human sensibilities
You are very obscure about what you dislike, how you would like them to express themselves, what would be those «human sensibilities» you meant here (that for all we can guess, may not be universal)...
"I mean", you wrote in the parent «that talks ... like a human». That surpasses the palette of "that paints like somebody holding a brush".
