Nothing. I'm 34 years old and grew up in the rural Southeastern U.S. We had a meager public library that was a 20-minute drive from my home. I spent as much time as I could get away with in my schools' libraries.
My entire childhood, I had the sense of a world much bigger than the one I lived in that was just beyond my reach. My mother could give me glimpses when we went on vacation, but I was living years out of touch.
When we got Internet access, I got connected in a life-changing way to that world. It transformed how I learn, how I discover, what I remember, how I connect with people, everything, and all of it for the better. I think I'd rather die than go back.
