Sure, there's a downside. But I think you're romanticizing the past in terms of social interaction in public spaces, and often the people that we talk to were indeed like us, at least geographically, economically, culturally. For instance, without the interwebs, none of us would know each other, and quite a few us know quite a bit about each other's lives that we would otherwise would not. Maybe to everyone else we're all just a bunch of soulless avatars, but not to me. When a poster hasn't posted for a while, I worry. And I'd like to think the feeling is mutual. Sure, we spend too much time on our screens, but I think that has less to do with social media or even the internet, and more to do with that we have a computer in our pocket; it has do with technology not global communication. That said, I understand where you are coming from.
