> The smartest kids are smarter than ever before

Only if they’re wealthy or get extremely lucky and live near a randomly good school. By many metrics I was the smartest in my class, but my family had little money and lived in a rural area with a single underfunded school. I spent my days in class with kids that were still struggling to sound out “cat” in third grade. A few times a week I got to spend an hour in “gifted” class but that was mostly art projects, nothing that would help make up for the rest of the day being wasted.
