This is valuable, but at a certain point the market of ideas relies on people actually engaging in object level reasoning. There’s an obvious failure mode in rejecting adopting new ideas on the sole meta-level basis that if they were good they would already be popular. Kind of like the old joke of the economist who refuses to pick up hundred-dollar bills off the ground because of the Efficient Market Hypothesis.
EA & Aspiring Rationalism have grown fairly rapidly, all told! But they’re also fairly new. “Experts in related fields haven’t thought much about EA approaches” is more promising than “experts in related fields have thought a lot about EA approaches and have standard reasons to reject them.”
(Although “most experts have clear reasons to reject EA thinking on their subject matter” is closer to being the case in AI … but that’s probably also the field with the most support for longtermist & x-risk type thinking & where it’s seen the fastest growth, IDK.)
I’m pretty sure “man” here means “human”, not “male”; and they’re referring to the idea that human intelligence evolved primarily for hunting purposes as part of a “get smarter > hunt better > get nutrition from meat to support brain > get smarter still” feedback loop. [This doesn’t have much direct implication regarding equality.]
