Because it's very much not a person, and it didn't learn anything.
A for-profit corporation simply scraped the net and fed a bunch of other people's work (the direct result of human labor) into a system of biased nodes and anthropomorphized it by calling it "intelligence" and "learning".
This is exploitation of labor of the working and creative class, nothing more, nothing less.
It doesn't have the agency of a human being, nor does have the creativity or individual perspective of one. It has no senses of it's own or lived experiences to draw from, and it is not sentient. Furthermore, it doesn't interact with the world or economy like a human being, it does not create things like a human being, and if has no human rights or even copyrights.
LLMs are not people, no matter how some people choose to treat them.
