I agree with banning smartphones during classes. They are incredibly distracting and I know i didn't understand the real value of that free education until well after I had graduated.
I also think less dependence on social media for staying in touch and communicating could help reduce loneliness and some of the depression and anxiety some people face. If we are less connected at our fingertips to people, we are more inspired to see and connect with them in person, which in my experience is more fullfilling.
