Or rather, who are you going to entrust with the task? 
    The same educational establishment that produced the 
    current populace?T

Ideally, education teaches critical thinking, not a specific indoctrination.

Education, obviously, often falls short of this ideal and you don't necessarily need formal education to be a critical thinker.

I do think that's pretty achievable. When I went through school in the 80s and 90s we weren't exactly devoid of this sort of thing.

Absurd ideas like chemtrails and flat-eartherism don't last very long in the face of the slightest hint of critical thinking.

    But even if you can produce your more educated populace,
    you still have the problem that the Russian trolls aren't
    going to stand still. They're going to be better, too, by
    then.

I certainly don't disagree, but doing a better job of critical thinking certainly seems like a reasonable first step no matter what else we do.
