> If today it takes twenty years of math study to reach the frontier ... Are you counting from when a kid first learn 1 + 1 = 2? That seems a misleading metric. The rate at which kids are learning math in the first half to 2/3 of their schooling is very low. Or are you asserting that Ph.D.'s don't reach the frontier until age 40+? Actually, the frontier of math is too far away for most humans to reach because >99% of humans don't have the drive and talent to study and learn enough advanced math. Similar barriers exclude >99% of people from Olympic-level athletics, or being famed violinists, or being important architects, or being US Senators, or being successful ancient historians, or many other things.
