It's a nice list, but I think the core point strikes me as liable to be simply false. I forget who it was presenting this evidence - it might even have been James Miller, it was someone at the Winter Intelligence conference at FHI - but they looked at (1) the economic gains to countries with higher average IQ, (2) the average gains to individuals with higher IQ, and concluded that (3) people with high IQ create vast amounts of positive externality, much more than they capture as individuals, probably mostly in the form of countries with less stupid economic policies.

Maybe if we're literally talking about a pure speed and LTM pill that doesn't affect at all, say, capacity to keep things in short-term memory or the ability to maintain complex abstractions in working memory, i.e., a literal speed and disk space pill rather than an IQ pill.
