This is just magical thinking on your end. I’ve met some of these “literal geniuses” making 500k at faangs and most of them are completely socially maladapted once you’ve taken them out of the pipeline they’ve lived in since high school to getting their first job mid or late 20s after their masters or PhD.
Secondly you started off this chain with talking about how someone working hard for 15 hours a day for decades is going to be more valuable and they’ll just be able to pick up every skill a human could have or need because they’re “geniuses”.
If they’re really geniuses why do they need to grind?
If you’re implying that they are only part of the set of geniuses that grind that long and there is another set of geniuses that didn’t, then how does that track with geniuses being a very small fraction of society?
