The Smartphone Theory of Everything probably doesn't explain all of the recent social changes, nothing is that simple, but it sure does correlate really well with all kind of trends since they became widespread. Casual socializing, partying, friendships, drinking, and sex all began to plummet around the same time, while loneliness and depression increased.

Anecdotally is makes a lot of sense as well. Most of the people I know, including myself, spend an awful lot of time on their phones and the internet in general. All of those hours have to come at the expense of other activities.

When I was in my 20s I spent an unusual amount of time (for the era) alone on my computer, but since most people were still quite social it was easy to hop into various activities. Now that nearly everyone is spending a bunch of time alone on their phone the real life social networks have begun to fray.

Some of the changes are for the better (ie. fewer teen pregnancies) but I think these trends are quite bad overall, without a clear solution. It's probably not a coincidence that political polarization and extremism has also increased during this time. Banning smart phones in schools seems like a step in the right direction, albeit a tiny one. Hopefully we can come up with more.
