I do agree that the last point is true - but see OP's message. I don't want to talk to you in the grocery store. If I'm standing there with Earbuds in, and you make Smalltalk with me, don't be surprised if I totally blank you or seen confused.
By the way, pubs aren't one of those really, as they're too unstructured.

I'm not sure what you mean by "third spaces", then.
It's more than the past 3 years. People really started coming unhinged in late 2016, by my observations. But the trend has been increasing for a while, and I'm willing to point a pretty sharp finger at the various social media, news, etc companies who are enabled in their "pour liquid oxygen on the fires of division for stoking outrage in the pursuit of more ad views" by things like the smart phone - because now someone is connected 24/7, by default.
Host firepit nights and invite people. I've yet to find a better solution to getting good actual conversations going than to have regular firepit nights (right now, I have one a week, and would like to get another few per month going this summer with different groups of people). Yes, some people will look at you like you're nuts, and others will turn into solid friends.
Fundamentally, I don't think we're going to fix the problems of smartphones and consumer tech (in the general "surveillance capitalism" sense) with more of that stuff.
