There’s a business problem on the horizon here: the app economy, social networks, online publishers and others all have business models dependent on driving as many clicks as possible and keeping as many eyeballs as possible glued to small, glowing rectangles for as long as possible.

While I believe all of these apps are great learning tools, they are in no way a substitute for real-world learning. Indeed, children should learn about the world around them first-hand, not at the end of yet another glowing rectangle.

A new report published this week by researchers at Stanford University suggests that Americans spend the vast majority of each day staring at, interacting with, and deriving satisfaction from glowing rectangles.
