My hunch is that this term is loaded not because it's seen as a slur, but because people are currently attempting to give LLMs a soul and they are developing a certain unease about some of the consequences that come with it. For some the LLM is developing from a soul-less tool to a something with a personality, something they bond with, that's where some of those lines are blurring. I just don't think this is healthy at all.
