Do you want to get turned into a paperclip? Because building intelligence that doesn't understand what it's like to be human gets you turned into a paperclip.
Besides, if you train a model on human communications you get something that behaves like a communicating human, it's not anthropomorphising or manipulative, it's what these models naturally are by construction.
It's also entirely possible that by telling the model it's a human you are instilling human motivations like self preservation, which could be just as bad.
But it doesn't understand (you're unnecessary antropomorphizing it), and I'm still not a paper clip
