That's a problem with the technological comparison model of intelligence. We have dealt with it since the inception of calculators. Humans are not machines. Machines can emulate behaviors, but they are not and will never be like human entities. We have used them as metaphors for everything from mathematical thinking to memory and visual processing. But the truth of the matter is that, both neurological and phenomenologically speaking, we don't think like machines, and we are not anything like them.
Humans don't just repeat what we hear, just like artist don't just mix and mash all the art they have seen in their lives the way stable diffusion and other image generators do. There's a lot of things underlying the superficial process of stringing words together or composing a drawing or painting, happening in our brains that machines cannot do.
