I often think of Isaac Asimov’s The Naked Sun, which takes place on a planet, Solaria, pop. 20,000. The entire population lives almost their entire lives in complete physical solitude, with robotic companions, and relying on holographic projections of friends and neighbors. They avoid almost all human contact, even being in the same room as someone has reached the point of cultural taboo. Procreation is done rarely, and reluctantly.
When I first read this 30 years ago, it seemed outlandish. Now, not so much.
In reference to the OP, though, human nature is adaptive. When someone is alone, or anti-social, it’s often not loneliness, because our social interactions are evolving into a different form. But it is frequently solitude, which is different, mainly in that there’s less of a stigma associated with it. The less contact we have with the outside world, the more adjusted to it we become. As much as 10 years ago, I wouldn’t have wrapped my head around staying inside to do all of my shopping. “Get me outside, where I can see, and touch what I’m buying!” My wife, on the other hand, being of a different generation, doesn’t hesitate to shun the malls and shopping centers. If she can avoid the grocery store, she does. She’d be a great Solarian.
Conversely, Social anxiety is on the rise. Even the culture outside of our living rooms is reflecting this.
Go into McDonald’s. There’s an ordering kiosk in front of the registers. You can order and pay, without the terror of interacting with another person. Those are used even when there’s not a line at the counter.
Go to a concert. A large portion of people are filming with their phones, not actually being present in the audience. Even when they’re right there, it seems as if the experience is being filtered through the comfort of the screen.

It does seem that we’re separating ourselves more and more from each other, and self-insulating against anything unpleasant, or uncomfortable. This encourages us to seek out others (virtually, of course) who are similar to us, and give us a sense of security; leading to an increased tribalism, and widening the gaps between people with different beliefs, and even tastes.
Is that getting worse now than it was in the past? I can’t answer that.
But I agree that we are seeing it more frequently, wired to the entire world in our immobility.
