Ahhh...that makes sense. 'Excessive' is a hard thing to define though, but I get where you're coming from, and agree. Balance in all things.
You're right about adults not being able to deal with it. I kinda think that more exposure in a controlled fashion as a kid is a better solution than less exposure, though, as well as teaching complimentary skills that are not necessarily tech-based, but are applicable to the tech-realm.
I have a little hobby-horse regarding critical reading, and I think it's more important than ever that kids are taught those skills. And they can be taught from pre-school age (after a fashion, anyways...) The more diverse and less controlled information sources become, the more important it will be.
I think the other thing is that use can demystify. I don't see computers as anything special, and haven't for a long time. I went nutso over my smartphone when I first got one, and now it's merely a tool (mostly, anyway). If I got a tablet, I'd probably love it, then find it just another tool. So I'm trying to get my kids to see things along the same lines.
Easier said than done, but I think technology, and access to technology will be ubiquitous, if it's not already.
