This calls for a calculation. How hard creating an FAI would have to be to have this inequality reversed?
When I see proposals that involve convincing everyone on the planet to do something, I write them off as loony-eyed idealism and move on. So, creating FAI would have to be hard enough that I considered it too "impossible" to be attempted (with this fact putatively being known to me given already-achieved knowledge), and then I would swap to human intelligence enhancement or something because, obviously, you're not going to persuade everyone on the planet to agree with you.
r/Fitness does a weekly "Moronic Monday", a judgment-free thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. I thought this seemed like a useful thing to have here - after all, the concepts discussed on LessWrong are probably at least a little harder to grasp than those of weightlifting. Plus, I have a few stupid questions of my own, so it doesn't seem unreasonable that other people might as well.
