Every generation has its adult fools who look to "young people" for wisdom.
But young people are idiots. They may be intelligent, they may be (relatively) well-read, and insightful, but WISDOM comes with experience, and teenagers cannot be "wise." At best, they can recognize wisdom in others and emulate or parrot the wisdom.
When you see an adult raving about how wise young people are, it is invariably a case of the adult not having sufficient intellectual horsepower to make his own case, and hoping that their point will be accepted from a kid.
There is nothing wrong with a kid being an idiot, but there is something wrong when adults pretend that their insights are wise. It's just spitting back what they heard most recently from their guru, be it a college professor or whatever.
