I read the entire article. Understood zilch, except for this:

Piccirillo’s proof appeared in Annals of Mathematics in February. The paper, combined with her other work, has secured her a tenure-track job offer from the Massachusetts Institute of Technology that will begin on July 1, only 14 months after she finished her doctorate.

That tells me that she and her accomplishment are pretty impressive.

I read the entire article. Understood zilch,

Oh good it wasn't just me!

I too read the article and I didn't even understand the question much less the answer.
