Someone like Paul Graham or Tyler Cowen is noticing more smarter kids, because we now have much better systems for putting the smarter kids into contact with people like Paul Graham and Tyler Cowen.
I’d guess very smart kids are getting more numerous and smarter at the elite level since I’d guess just about everything is improving at the most competitive level. Unfortunately it doesn’t seem like there’s much interest in measuring this, e.g. hundreds of kids tie for the maximum score possible on SATs (1600) instead of designing a test that won’t max out.
(Btw, one cool thing I learned about recently is that some tests use dynamic scoring where if you get questions correct the system asks you harder questions.)
