I wonder if we're entering an era of social stagnation, caused by screens. Before screen-based entertainment was so ubiquitous, young people (teens and young adults) experienced a lot of boredom, which pushed them to do new things. Many of those things were stupid and bad (drugs etc.), but some of those kids decided they were ambitious and wanted their life to be above ordinary in terms of achievement and impact on the world. Today, there's less room for such thoughts to even emerge - and if they do, they have to compete for mindshare with addictive entertainment on a daily basis.
