I'm not sure a larger population is exactly the best way to go about achieving some of those goals, specifically: "More Geniuses". I feel as though there is a counterfactual of "More Idiots" and "More Jerks". I think it's questionable that "geniuses" even contribute to society a meaningful amount. I think I'd more value a larger amount of people with above current average reasoning and societal productivity (which larger population might actually help with).
