Screens are a medium. I don't see how they are inherently bad, although it is probably correct that screens carry the most bad content out of any information medium. But my kid has learned how crayons and instruments are made by watching Mr Rogers, and I simply don't see how he would have learned that via some other medium in the same amount of detail (visual and auditory together). He has seen jazz and classical musicians explain and play their instruments. He has seen how adults interact with each other and respect one another through Mr Rogers and (older) Sesame Street. I've then seen this translate into his real world behaviors. You think that is fundamentally bad?
