Motivated by an apparent counterexample to the Weak Gravity Conjecture, I will describe the difference between black hole extremality bounds and BPS bounds and (relatedly) the difference between superextremal particles and self-repulsive particles. This will lead us to some novel connections between BPS state counting, Calabi-Yau geometry, supergravity, black holes, and several Swampland conjectures.
