I really think it's a matter of context; how one was raised, what kind of people one interacts with, interest, etc.

I'm older and i know so much more than most of my age group. I learned a long, long time ago to not be afraid to try things out, my pc is not going to explode; to investigate when i'm stuck with some computer stuff; and i have adult kids who teach me things that i don't know enough about or share their views. Some of the communities i subscribed to are about tech, FOSS, android etc. I'm always really open to boost my knowledge.
