Although best understood in flat space\, generalizat ions of the WGC to other spacetimes such as (anti) de Sitter space exi st\, although this typically leads to undetermined O(1) factors. In th is talk\, I will give a new perspective on the WGC by relating it to t he absence of a black hole instability known as charged superradiance. I will present preliminary results that suggest that this gives a uni fying picture of the WGC in flat space\, de Sitter and AdS which fixes the O(1) constants.
