If Y is a curve of genus at least 2 over a number field, then the finite descent obstruction cuts out a subset of the adelic points, which is
conjecturally equal to the set of rational points. In particular, we expect this set to be finite. In this talk, I will present ongoing work with Jakob
Stix proving that certain projections of the finite descent locus are finite, as predicted by this conjecture. The method we employ can be
loosely described as "Lawrence--Venkatesh for Grothendieck's section set".
