An adult's understanding of how people behave, and a parent's desire to give their children a better life...not a 21 year old's ignorant view of the world.
People here, of all the people, know better that wisdom is not based on age. It is rare at young age, but not impossible.
Now if a 35 year old were to come along and outright dismiss him because he's too young, oblivious to how bad that would look to a herd of hackers, then that would challenge your assertion that wisdom is earned from experience.
My moneys on the 21 year old
but hey, I'm 25. You know us young fools, right?
