Did a small survey last year on this point and discovered that while technology might sound distracting people are actually spending more time reading/viewing stuff they like more lot more than before.

We found that among teens for example very few people read anything from news websites very rarely but almost every single teen had read at least one article in depth on very niche topic that appealed to them. (For example reading about affairs for their favorite pop star). Most teens performed very poorly when they were given 1 hour and asked to prepare a presentation on "any american hero".
