I find it ironic that this perspective is being shared in such a "thin" way.

There are some insightful observations but the whole thick/thin perspective just doesn't resonate with me. As an old man (shakes fist at clouds), we have stopped prioritizing people. It is all about building and maintaining relationships and we've gotten lazy. And maintaining relationships is a lot of work and without it we do feel more isolated. So we try to fill that void with things that don't require effort like buying crap we don't need on Amazon and chasing likes on social media. We aren't happy so we try to be busy so we don't notice so much.

We saw a bit of a teeny correction during covid when people starting going outdoors and baking bread and cooking home cooked meals. But now everyone is back to working from home in their pajamas and tell themselves how happy they are with all the time they save not driving but skip over the lack of adult interaction (both good and bad).

But the problem is easily solved for each of us by things as simple as hobbies and volunteering and organizations (church, civic, etc.) Personally, I design board games and have friends over to test them and go to board game conferences. We've built a group that still test and communicate online but are happiest when we get to hang out and play games and go for dinner. There is no shortage of these opportunities but you have to get off the couch and join in. It is a place where you will make new friends and find happiness but you have to decide it is worth it.
