Lazy, yes. Stupider, not entirely.
If we do not want to do something, we create something to do it for us. We didn't want to get up to change the channel on the tv, so we created the remote control. We didn't want to flip the light switch from across the room, so we invented the "clapper" so we could turn on the lights from the comfort of our bed. We try to get others to do what we don't want to do. The sneaky way, normally.
Not all of us are stupid, though after watching the "Jersey Shore" we have to doubt our society. I know a few children who are beyond intelligent. A 13-year-old who taught a computer class at the community college. An 11-year-old who created an app for the iphone. Many duel-credit students, devious young males creating explosives, etc. They are there. You just have to find them.
