I do think the Internet has escalated it dramatically. It's not a "steady decline" so much as a free-fall plummet. And we can barely analyze and wrap our heads around what's going on before it's shifted drastically again.
But like every new technological invention, there are people who will eagerly abuse it and overuse it to the point of damaging their social skills and behavior, and people who will use it to great advantage as it was intended.
If you think of Internet communication as "means" rather than an "end" you're on the right track. If this is "where the train stops" in your social world, that's not healthy. It is not a substitute for face-to-face human interaction or focusing on the people standing in front of you (physically). Learning how to deal with people who may have differences of opinion and actually speaking to them is a lot harder than just "clicking away" from them on a website page, hiding behind a phony name or avatar, or hitting the "block" button. There's no social skill involved in that.
People were not meant to be "channel-surfed through." And what the Internet does, that is perhaps most damaging of all, is to trivialize. When people are so busy clicking buttons, surfing along, and living in the moment, down to the millisecond, that they don't actually stop and think about anything or anyone, their entire daily life experience becomes a meaningless barrage of four-word status updates, pointless text comments, and exclamatory reactions to things that are forgotten immediately after the "send" button is hit. There's no relevance to any of it.
