Weak geometric lemma for ADR boundary of a uniform domain implies uniform rectifiability

We resolve a conjecture of Guy David and Svitlana Mayboroda. We show that if $\mathrm{\Omega }\subset {\mathbb{R}}^n$ is a uniform domain with $(n-1)$-dimensional Ahlfors David regular boundary $E=\mathrm{\partial }\mathrm{\Omega }$, and if $E$ satisfies the Weak Geometric Lemma, then $E$ satisfies the Bilateral Weak Geometric Lemma. In particular, $E$ is uniformly rectifiable.
