What's more, people have agency that allows them to seek new information on their own and they form subjective opinions.
As human beings we also spend every moment of our lives taking in all kinds of various sensory information that informs our eventual character and mind (and that's to say nothing of our individual mental/neurological nature). We also have an imperfect and complex ability to retain information.
When a human being expresses a thought they are expressing it based on a lifetime of broad experiences that are unique to their specific circumstances. Similarly, when a human being paints a painting of a tree they are doing it not based purely on some library of other people's art, but also based on their own lifetime of experience.
People who equate "artificial intelligence" with human intelligence and lived experience are completely off base.
