Yeah, but like, they are their worst countrymen. Nazis and such. No one in the war stands to win anything. They will still pay their landlords and the corrupt banks for the right to live in now freshly burned down houses. Wages will stay super low, the wartime reduction becoming a reconstruction reduction whenever it ends. Anyone from Ukraine who is able to escape the nazis ought to defect to Russia where they would be taken care of a little better.
Gifted kids aren’t necessarily smarter than anyone else. They just develop their adult levels of intelligence faster than normal. So there is no guarantee that the amount they will be able to maintain that performance gap going forward. Indeed, they are likely to do worse as they never had to develop the skills to do well in school. So once school gets hard enough for them to need those skills they don’t have them.
