I agree with you. I also grew up 50 some-odd years ago and look back fondly on those years when every daylight hour outside of school would be spent climbing trees, exploring creeks, playing pick-up baseball games and roaming the wider neighborhood with a pack of friends.
The radical change that's taking place now is not specific to any generation. It's a case of modern technology overwhelming the ancient human brain. We are a social species and evolved in small tribal groups. Our brains give us positive feedback when we interact with others. We get a small jolt of dopamine when we socialize. We get a feeling of security and connection which are valuable for building tribal cohesion.
The trouble comes when you are able to pull a little electronic slab out of your pocket and get this little burst of pleasure on demand. It reminds me of old movies from the 40s when everybody whips out a cigarette at any available moment. Social media is addictive. I go to a restaurant now and a good 80% of the other customers either have their cellphone in their hands or sitting on the table by the plate where it can be constantly checked. It's middle-aged people just as much as young people doing this.
What's getting lost here is a sense of self and self-reliance. The ability to be content when alone is an important part of adulthood. I've never liked the idea that I walk through my life and anybody in the whole world can reach out and ring a bell in my pocked, demanding my attention. It's like being on a tether. I cherish my independence as well as my social connections.
But this seems to be getting lost in any general sense. People seem to be developing an early form of hive-mind where constant connection with others is demanded.
