100% of the training data of the salty jelly in a human skull, is a sensory input.
Were your argument flawless and your conclusion correct, then all human creativity would "literally" be a remix of things in the natural world, as even when we remix things made by other humans that too would ultimately derive back to nature.
This can certainly be asserted depending on how you wish to use those words, but just as it is not useful at predicting what our abilities are — for example, a perfect intellect could predict quantum mechanics from scratch by watching a camp fire die down on a rainy night, but we didn't do that in one step in the neolithic — so too this isn't useful at telling us what the limits of GPT-family LLMs might be, as that which has been built on such inputs, both in the case of humans and this particular AI, greatly exceeds the imagination of any single individual.
