Why is it being called dead internet theory when, as far as I can tell, what's really happening is that big centralized systems are being overrun with bots? The internet existed and was pretty great before these large centralized systems came into being.
Anyone can still run a blog/website, and/or their own discourse server. There's no need to mourn for these centralized systems that largely existed only to exploit us in some way. Let's celebrate "small internet theory", an internet where exploitation is effectively impossible because every company that tries it is overrun with AI bots. That sounds awesome to me personally, but I was also up late last night watching clips of Conan O'Brien from 1999 and the nostalgia for that era / what the internet was like back then hit me so hard it was almost painful.
You can create a blog, yeah. But you also can write the blog with AI. So, you still need to filter the content. Over time, people will find that "The signal-to-noise ratio has hit a breaking point where the cost of verification exceeds the expected value of engagement." https://arnon.dk/the-trust-collapse-infinite-ai-content-is-a...
And check these books "Superbloom: How Technologies of Connection Tear Us Apart" and "No Sense of Place", maybe it would help you to see the overall effects of the internet (and other communication mediums) and forget this simplistic view that a lot of programmers have. The nature of the communication medium doesn't just affect the message, it shapes everything in society. Ignoring that because you had a good experience here and there won't change anything.
