What is more important, raising next generation of Musks (albeit ideally much less broken sociopathic piece of shit as current one), or avoiding next generation of Trumps?

Both of those can add tons of societies (or avoid their downfall), but all of them have 1 in common - they are spoiled rich kids with 0 connection to lives of ordinary folks from Day 1. One of biggest tricks Trump pulled was convincing folks he is one of them, and understands and shares their plight.

So it seems we are already getting at least aome brilliant folks up where they belong, and lower rate of those ain't outright catastrophe for aociety. On the other hand - dumb trivial to manipulate general population can't be saved by producing more smart brilliant folks, populistic corrupt a-holes will still overcome them.

So I would focus on general education level much more, based on above. General prosperity over future trillionaires.
