Exactly! The code used double as "proof of work". Well-formed language used to double as "proof of thinking". And that's what AI breaks: it speaks, but doesn't think. And my core point is that language that does not originate from well-reasoned human effort (i.e., from either writing the language directly, or from writing such code manually that generates the language deterministically, and for known reasons/intents), does not deserve human attention. Even if the "observable behavior" of such language (when executed as code) looks "alright".
And because I further think that no code should be accepted without human review (which excludes both not reviewing AI-generated code at all and having some other AI review the AI-generated code), I conclude that AI-generated code can never be accepted.
