I would be willing to bet that any human for which we spend $100billion - $3 trillion (depending if you want to count single corporations or global totals) on in an attempt to make them as capable as possible would be able to reach all of those levels.
You'd get rapidly diminishing to zero returns after the cost of university a few times over. Every dollar past that would produce no performance gain beyond that.
Are you imagining artificial augmentation somehow? Purely through tutors or training programs we seem pretty limited. Otherwise billionaires (or even multimillionaires) could have far more consistently successful kids.
I think I view humanity fairly positively, but I admit I would gladly take the other side of that bet
