I think art that spreads the "politics is the mind-killer" meme (which actually seems to be fairly novel outside LW: 1 2) could be a good use of art. Some existential risks, like nuclear weapons, seem likely to be controlled by world governments. The other day it occurred to me that world leaders are people too and are likely susceptible to the same biases as typical folk. If world leaders were less "Go us!" and more "Go humanity!", that could be Really Good.

Welcome to LW, by the way!
