What's changed is social media. Twitter, Facebook, Reddit, YouTube, Instagram all use machine learning to provide just the right feedback for us to keep cominng back for more. This has hijacked our dopamine feedback loops and changed the way we interact with each other. I know personally, my attention span is much worse than it was years ago. It's tough to find friends, and if I weren't married, I bet it would be tough and highly competitive to find a mate. I think this has something to do with it.
