Even if you (even strongly) support EA, I don't know how we could justify this being at 80%. e.g. I probably agree with people who would want to minimize animal cruelty during the Renaissance, but all 3 of them could hardly be considered a "beneficial movement" for me to look back on because, well, the movement part didn't really...

This question is really "will people see EA as beneficial" AND "will EA be a really really big thing in the historical record."

if they say “oh, our ancestors wasted an inordinate amount of resources not doing eugenics” but we eventually did eugenics, how would this resolve?
