Unlike the author, I don’t think that the internet is dying, but instead entering a new phase that resembles in some aspects the old internet: search has become unreliable and those mega-platforms enshittify themselves to death, so people shift to smaller (often non-commercial) platforms and find new content to follow by the hyperlinks provided by other people. It’s a lot like the internet before Google Search.
It is definitely feeling like this is a trend, we are moving back to more curated ways of sharing information.
The Fediverse feels like a return to the old, open Web before it was captured by Big Tech, just with new bells and whistles attached. With all the enshittification, it seems like it is well-placed to be the solution to the problem. It's not there yet but it's a start.
