It's a negative feedback loop too. There used to be people out doing things so when folks got bored they'd go find them.

Now entertainment and social media sort of fill that gap (not really) but enough that there's less people out. Less people out mean it's less entertaining, so less people go out etc.

Incredibly pedantic, but I think that's describing a positive feedback loop where the previous result amplifies the next result further.

And when you do find people out, they're wearing headphones and/or their nose is in a screen, and if you try to talk to them they look startled and annoyed like how dare you speak to me in a public place. The culture is just gone.
