They are not "taking". They are copying. They are just MUCH MUCH MUCH better at it than humans. Also, there are probably millions of small changes in that "exact copy" that you cant see because your eyes cant tell the difference. It looks identical to you, but quite different to the AI. They were literally written to copy. When they talk to you, they are not talking to you, they are using values to determine what the most likely response would be based on other responses they know of. Also, stop treading AI like it is a person stealing soemthing. Sure, the company that runs it might have fed it info they shouldnt have, but that is the human, not the AI. AI is just spitting out what it is asked for. Guns spit out bullets when you ask for it with a firmly squeezed finger.
