This is a crazy take.
Yitang Zhang was "unknown" *because* math is *not* a meritocracy. He was kicked out of mathematics because his advisor didn't want his own errors uncovered. Other mathematicians didn't give a @$#!. Zhang lived in his car, worked at Subway.
This is the exact opposite interpretation of what actually happened. The case of Yitang Zhang perfectly illustrates how mathematics culture, at its best, is a pure meritocracy. Regardless of how “unknown” you may be, write a paper that proves a longstanding problem and we will read it, and if it’s right, then you will be instantly recognized as a hero by the community.
This part of mathematics may now be gone forever (due to AI), and this is very sad; this is one aspect of what so many of us are mourning, even as we look with awe at all the amazing discoveries we’ve already been gifted and many more sure to come.
