More like modern 13 year olds are not even 13 years old. I actually had responsibilities when I was 13, and I could drive a truck at that age.
Modern kids are mostly pathetic, and it is a terrible shame how much of a childhood they really miss.
To the matter of cognitive abilities of 13 year olds, if you are suggesting that they are capable of understanding the dynamics of the Kirk-Spock-McCoy, Luke-Han-Leia, or Rey-Finn-Poe triangles, I disagree. Thirteen-year-olds are not experienced enough to grasp the subtleties.
