I could. i would get adjusted to it in a few months. Hell i didn't even have the internet until i was 15 or so so i've only had it 9 years. I spent the first 15 years of my life w/o the internet. i'd adjust in a few months, but it'd be a bad few months. I'd have to start going to the library again whenever i wanted info.
I remember when i was like 7 i was interested in swords and wanted to learn about them. The only info i could get was from an encyclopdia article about them, 2 paragraphs or so. Now i can get endless info from all over the world. It would be hard to give that up.
I also remember recording songs on the radio via cassette instead of downloading them.
Lets not forget the PC games or the fact that virtually all SNES, NES, genesis, etc games are free online.
And all the friendships you build online. Its so easy to be yourself online, hard to give that up and go back to just interacting in person.
Jesus, it would be hard.
