You want a real conspiracy? Here is mine: Why do theories as sophomoric as "dead internet theory" and "NPC theory" or "simulation theory" or "Roko's basilisk" get *any* oxygen at all in media?
These are half-baked shower-thoughts at best.
But they are also concepts that teach helplessness and self-isolation.
If you were the kind of person who feared the internet as a tool for grass roots organizing "dead internet theory" would make all would be activists dead in the water.
