I think that there are three relevant artifacts: the code, the specification, and the proof.
I agree with the author that if you have the code (and, with an LLM, you do) and a specification, AI agents could be helpful to generate the proof. This is a huge win!
But it certainly doesn't confront the important problem of writing a spec that captures the properties you actually care about. If the LLM writes that for you, I don't see a reason to trust that any more than you trust anything else it writes.

I'm not an expert here, so I invite correction.
