I'm just tired of you asking these questions just so you can showplace your parenting skills in light of other parents. I see kids who are highly plugged in who are also highly motivated and highly creative. I see kids who have no access to electronics who cannot follow simple directions. And everywhere in between. Because I have worked closely with well over 1000 kids, my observations are not simple anectodes. In fact, they learn much more from, for example, an interactive virtual field trip to Galapagos National Park than they do in the dusty old textbook. Part of it is what they are born with. Part of it is what they are exposed to by their parents.
Humans existed a long time before written word and many were creative and intelligent. We have left the age of literacy and are fully entrenched in the world of technology that wasn't available to us dinosaurs. We who were raised in the age of literacy cling to it as a measure of character depth, even though most folks raised on book learnin' hardly pick up a book as adults and embrace the tv. We might stem the flow of technology in our own individual children or students for a time, but they will leave us behind in a handful of years and turn around and teach us how to navigate the new world.
As for television versus a book, if both are presenting the same subject, for example a civil war battle, the television is more engaging and most kids will learn more from it. We 20th century folks highly value literacy so we place more value on the book, but our kids won't.
I was making broad observations about the world at large and not about my individual situation because that is anecdotal. Personally I prefer the old ways, though rely heavily on technology for my job and my schooling. It seems obvious to me why I would password protect, but I will explain it for you. I block access to violent or overly sexual content because it is not age (or human!) appropriate as I would with anything we have access to, technological or not. Of course I would expect all thoughtful parents to proceed with caution and with limits. This doesn't change the bigger picture of technological advancement. As you said, the word is going faster.
