I mean then is DIT really a conspiracy theory? I know that people in HN have already started doing replies with AI in some threads. (only because they tell people). Wait a few more years and there will be no way to know if forums are just bots generating content.

I guess HN would be a weird outlier, because there are no ads. Except maybe the bots would be useful after all when various "Show HN" or "Launch HN" and have the bots cheer those companies and get random publicity.
