I don't believe children in the 23rd century would do that. Like, in the present day, if I made a paper plane that didn't fly properly, someone might say "I can make my plane better than yours". But someone with more evolved sensibilities might say "Your center of gravity is off, and your wing tips need to be further back". Even children in the 23rd century don't do "I can run faster than you" or "My dad could lick your dad".
