Nowadays we read a Wikipedia article or watch a Youtube video on a topic but never interact with the content. It's all very passive. I was a child during the heyday of Encarta and I remember I had it and a few other specialized encyclopedias (one about animals, one about sea life, one about dinosaurs!!) and they were all interactive. I miss this about computers. Not all things have to be a game or passive which is what I see nowadays when a child has a screen in front of their face.
