Not true. Not even humans have that level of manipulation. We employ humans despite the lack of these features. That means these baseline features are 100% fully negotiable. They're negotiable all the time because we employ humans that DON'T have these features. Thus LLMs don't need the features either. Either way, we don't understand LLMs well enough to even predict whether future modifications will or will not have the features you claim. Such a hardline claim that it will never "fully be there" is illogical. Nobody predicted that transformers could lead to LLMs, nobody can predict what LLMs will lead to.
