Serre long ago raised the question of whether there exist motives with motivic Galois group equal to any given exceptional algebraic group. I will begin by situating Serre's question in the context of a quite general inverse motivic Galois problem, and by recalling some Hodge-theoretic and l-adic variants. After summarizing progress on Serre's question due to Dettweiler-Reiter and Yun (for the groups G2, E7, and E8), I will describe recent work constructing geometric (in the sense of Fontaine-Mazur) l-adic Galois representations with any desired exceptional algebraic monodromy group.
