When it's gone, the "old internet" will be gone
There are still some of us that are trying to keep the old internet alive. (Shameless plug: https://beta.getaether.net )
One of the problems with attempts to keep the "old internet" alive is that they still skew technical (because most of the people who are nostalgic for it are comfortable enough with those technical things), but now regular Joes have other options. They're not going to bother learning the technical stuff if everything else is set up to make it brainless and easy.
Moreover, since you HAVE to be technically inclined to build such a thing, the initial word of mouth and distribution winds up being constrained to the technical crowds. This makes the communities one-note and boring, so people just don't feel very compelled to stay.
