That's a bit harsh. "Content" can mean a wide variety of things, and smartphones/tablets are capable of displaying such a wide variety of things.

We strive to curtail our own usage of devices around our young daughter at home. The extent of her screen time is maybe 1-2 movie nights per month.

But she and I do around 5-10 minutes of Duolingo/Pimsleur every day. She asks every morning if we're going to "do French" today (even though we switched to Hungarian for most of this year).

Are we fully exploited?
