The concept itself is pretty amazing to think about, but I wouldn't expect the long-term implications of intelligence to play out nearly as dramatically as the author implies. While coming from means AND having high intelligence would confer benefits to be sure, there has to be a law of diminishing returns on increasing intelligence. For sure, the short-term inequalities would be difficult to keep in check. But if the entire world has increased intelligence then those benefits will quickly deteriorate.
