Thoughts
I think dead internet theory is a useful reminder that what makes us human is not on the internet, and that it's easy to forget that the
people on the internet are human. Some people take Dead-Internet-Theory as permission to dismiss anyone who has a controversial opinion or a lot of time online or a weird writing style as a bot. My take-aware from DIT is that we should be looking for the humanity, the humans online, not that we should be looking for the bots.
Also, DIT predates generative AI by quite a bit.
