I can prompt ChatGPT right now and ask for mountains of more "mathematical work"; thousands and thousands of pages of nonsense for you to review. So you can "be informed".
But you can't do it with their internal model that is the same or a successor to the one that solved the navier stokes millenium prize problem.
With 40% formalized they probably have a good idea of how many were found to have fatal issues in the formalization attempt, and they hired some mathematicians to verify some of them, especially the big headline ones.
But you couldn't make me review it. Anyway I think you're just straw manning what I was trying to say. I probably didn't express it terribly clearly and I'm not invested enough in this debate to put any more time in.
