My point is, the AI could not have done what it did without the skilled mathemetician prompting it. It was just a tool in the hands of the human that did it. And that was a very skilled human. Unless you're a professional mathematician, you cannot get the same result even if you use the same AI model. That's the proof that it's the human's work, not the AI.
Why don't you try getting a Millennium Prize then? If you think it was the AI that did it, you have access to the exact same ChatGPT.
