Interesting stuff from the comment section.
Gregory Cochran:
Only some, not all, human populations produce any significant amount of science, and there is no sign that is about to change. Every one of those populations that does produce science has sub-replacement fertility and is also undergoing selection for lower IQ.
Gwern:
One of the more interesting ways science may die is something I call the ‘Agularity’: the average age of productivity keeps rising, so at some point either no one sane will invest that much of their lifetime into maybe being able to contribute or there will simply be too little time to do much new work before the normal decline with age starts around 40-50.
Jones has a series of papers on this aging phenomenon: “Age and Great Invention” 2006; “The burden of knowledge and the ‘death of the Renaissance man’”, 2005; “Age dynamics in scientific creativity”, 2011; etc.

What happened to the Flynn Effect?
I'd note that average intelligence is largely irrelevant here. My guess is that with selective mating, the tail has thickened at least at the top end. You know anything about this? Of course, if they always just renormalize the tests to make them gaussian, it will be hard to see.
