Some things I appreciate but which I used to not appreciate: The Bernstein center, \infty-categories, etale cohomology, L-packets, perverse sheaves.

Some things I still don’t appreciate: Monads, endoscopy, rigid cohomology, A-packets, Springer theory.

  1. I like this post. Although I can’t agree with you on A-packets. They turn out to be super helpful in telling when Eisenstein series (or really, CAP representations) appear in cuspidal cohomology, and this is moreover helpful for p-adically deforming them. That’s why I appreciate them at least.
