I think you are thinking of "Locke" and "Demosthenes" in Ender’s Game.
By 2016, anonymous online political commentary was directly influencing major world events.
To me the idea of kids posting on Internet forums and becoming major political leaders through their pseudonyms, through logical language like a modern-day version of the Federalist Papers, does seem pretty silly in 2024.
Just looking at political commentary from the 80s and 90s, it's mostly nonsense.
