Note that some popular effective altruists have a little bit of tunnel vision when it comes to X-risks, which leads them to overfund X-risk-due-to-AI over something like, say, X-risk-due-to-asteroids. (X-risk-due-to-nanotech is being suitably supported by not funding nanotech.)
Plus, some people working on the AI X-risk problem are doing it for nothing, which means the state of funding is a bit weird.
