The first year or two of human learning seem optimized enough that they’re mostly in evolutionary equilibrium—see Henrich’s discussion of the similarities to chimpanzees in The Secret of Our Success.
Human learning around age 10 is presumably far from equilibrium.
I’ll guess that I see more of the valuable learning taking place in the first 2 years or so than do other people here.
This reminds me a lot about what people said about Amazon near the peak of the dot-com bubble (and also about what people also said at the time of internet startups that actually failed).
