Let g be a finite-dimensional simple Lie algebra. A classical question of Kostant asks whether the universal enveloping algebra U(g) surjects onto the space of ad-finite linear endomorphisms of some g-module M. In this talk I will comment on the importance of this question and give a survey of classical results for highest weight modules, including a recent negative result for type A.
