Sure, the internet was a lot faster at becoming ubiquitous, but humans are still humans. Our society still needs time to adapt to internet, because 25 years old, as you point out, is really not that much on the scale of a human life or an institution or society.
People under 30 do not remember the world without Internet anymore; 25 years is a generation. That said, it is really too soon to proclaim any final judgments.
My parents didn't know what WiFi was, internet culture was still largely for nerds, etc.
It took roughly 30 or 40 years for the press to be widely distributed around Europe.

> I think the ubiquity of the internet is what makes people comfortable to judge it as if it is mature.
Technology isn't going to stay exactly the same indefinitely. It just seems like a complete lack of imagination about the future to me.
I always go back to the printing press analogy. It took about 50 to 100 years after its invention for serious societal change to start happening: The Reformation, Counter-Reformation, birth of Protestantism, etc.
Give it time. Networked communication is just getting started.
