Every modern good, service and machine is helping to create a society with less real social interaction, and has been for decades. We're only feeling it now because we're reaching the horizon of not having to directly interact with another human being, ever, while still being able to take advantage of many other aspects of modern life.
The real lamentation is that the lack of interaction is perhaps less of a "choice" and more of a necessity for many people. Casual socialization is becoming a privilege reserved for the people who can afford to indulge. Everyone else is too busy getting by, and will choose the path of least interaction because they can't afford the inefficiency. Economic pressure over generations may make introverts of us all.
