Not all 80,000 mathematics Ph.D.s are actively working on the P=NP conjecture or theoretical computer science. The field of mathematics is vast, encompassing areas like algebra, topology, geometry, number theory, applied mathematics, and more. Even within theoretical computer science, many researchers focus on topics unrelated to P=NP.
The number of people specifically working on P=NP is much smaller, likely in the hundreds or low thousands. This includes specialists in complexity theory, algorithm design, and related areas.
Additionally, many researchers focus on partial results, new perspectives, or adjacent problems rather than attempting to directly resolve P=NP, given its difficulty. If you're pursuing this question, you're in a niche groupβpossibly among the most dedicated thinkers tackling one of the biggest open problems in computer science!
