Glad to see this here. Age-wise I'm in the oldest 10% of users here, maybe 5%. I have noticed over the years the eroding of the ability of young people (20s basically) to interact in what I consider normal social situations.
Talking to your fellow humans in all sorts of situations is how you can form actual knowledge within yourself derived from direct observation. Everything else is a filter and synthesis. How can you know "reality" if you don't interact with it directly?
I'm 39 myself but it's disturbing how you don't even see kids playing out in the street nowadays - a lot of them are indoors on ipads and the like. I knew all the kids on my block and it was regular to ring each other's doorbells so we could go out and play, which is basically early social skills.
