Unfortunately, in my class of students, being good at solving Olympiad level questions did not turn out to be a good predictor of their contributions to society.

Romania's current president is an international math olympic with two gold medals. We'll see how he turns out as a president. He's inherited quite some pressing issues and the President doesn't have all that much power. The parties made sure to neuter that institution. The alternative was a footbal hooligan with allegedly Russian funding behind him and a right wing discourse. Society is very polarised. Nearly half voted for the hooligan. Before, in the cancelled elections they voted for a nutcake Russian funded secret service puppet with a nicely sounding discourse void of any actual content and a very ballsy but quite dim witted woman, mayor in a small town. The Russians bet their money on multiple trojan horses, just in case one of them gets disqualified.

OTOH I am very impressed with how Volodymir Zelenski turned out. Who would have thought?
