So why do you think it is a structured formal thing?

It is a "structured thing" because it has concrete definable grammatical rules, shared across essentially every language and dialect, and common features, like an infinite range of expression and recursion. If language didn't have syntactic structure we'd just be yelling signals at each other, instead of doing what we're doing now. There would be nothing for GPT to capture.

Oh, it is clearly structured. Words and phrases and sentences are all forms of structure and we're using them right now.

What it doesn't have is formal structure; it cannot be fully defined by any set of rules. This is why you can't build a rules-based parser that understands english and have to use an 800GB language model instead.

>shared across essentially every language and dialect

Noam Chomsky thinks this, but the idea of a universal grammar is controversial in modern linguistics.

I'll leave it to the linguists to debate UG and the specifics of what it does and doesn't mean, but commonalities like some sort of hierarchy, recursion, structure-dependence of rules, etc clearly exist, whatever you want to call them. By shared I just mean there's specific things that human cognitive faculties are set up to do and then other (often computationally simpler) things they clearly don't do. But again, if you're just saying natural languages are not formal languages, I guess that's true by definition. It just sounded to me like you were implying something different.
