Habsburg AI? My sides went into orbit. I didn't know that I needed to know this expression!
I don't fully agree with the author but that was an enjoyable read. The initial chunk about Reddit is mostly there to provide context for the general trends and directions that the internet is following; the "core" is the impact of generative models into the internet.
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.
If that's correct, the impact of those generative models was only to speed up the process, not to cause it. At the end of the day the main concern is that it works a lot like spam - as undesired content avoiding being detected as such, and tweaked to steal your attention from the content that you actually want to consume. And spam is not something new for us (or the internet), what's new is GAFAM and their vassals (Twitter, Reddit etc.) eating it for lunch.
