Thank you for examining this crucial aspect of the evolution of human society, which has scrambled our intuitions of introversion and extroversion. We truly need to understand what is happening to us better.

It sounds like Thompson sees introversion as a behavior and you see introversion as a personality trait. So there's a semantic element to this issue.

The outside world today forces what looks like introverted behavior. One takeaway is there are a lot of frustrated extroverts, because a part of them yearns for a more social life.

(Of course they could continue to genuinely socialize, but techno-culture provides so many disincentives.)

But to authentically introvert, you need to have the personality trait. If you have it, you can be happy alone.

The thing is, the trait and the behavior are interrelated. Introverts are often social with other introverts -- because they enjoy having like-minded people to talk to.

But an introvert will choose "introverted" behavior -- being alone -- because it's painful to be rejected by extroverts who prefer shallow talk, and because shallow talk is intrinsically unpleasant to introverts anyway.

So "introversion" in a person can be a personality trait or learned behavior, or a mix of both. But I'm really glad you described the personality trait, to distinguish trait from behavior.

An additional feature or description of introversion -- which is implied or derivable from your piece -- might be someone who finds their inner world as rich as the outer world.
