Links between Geometric Group Theory and Number Theory
I don't think Church/Farb found a new proof of the prime number theorem, but rather a way to count irreducible polynomials (of given degree) over $F_q,$ which was first done by Dedekind [I believe], and is a matter of simple combinatorics (it is an exercise in Knuth volume 2). Also, I would not call this Church/Farb work "geometric".

Thanks, but why would one do such a thing? Presumably you want to prove your large deviation result with a given measure....

Uniform bound for the number primes $p$ s.t. a polynomial has a root modulo $p$
The results of Oesterle (as quoted by Serre) and LagariasOdlyzko were conditional only (on the GRH for the appropriate Dedekind Lfunctions), I thought.

Uniform bound for the number primes $p$ s.t. a polynomial has a root modulo $p$
I think just stating the main conditional and unconditional theorems would be useful. By the way, I notice he does NOT thank Oesterle, who claims to still have the notes of his '75(?) unpublished work, and since he is not really interested in working on it, maybe he can share them with Winckler  his claimed (conditional) constants are a bit better than Winckler's...

Wow, I did not know about this paper! The guy should get a medal for cleaning this up!

Why was John Nash's 1950 Game Theory paper such a big deal?
@SylvainJULIEN Is that why he got the Nobel prize? I believe that was the OP's question.
