Indeed, we're used to assign agency only to ourselves. But that's simply our anthropocentric mind speaking. We're systems and LLM is also a system. And the fact how useful LLM seems compels us to evolve it and replicate it. Same as a virus presents itself as valid RNA to a cell, and a cell is compelled to replicate the virus.
An LLM doesn't have to "want" it itself, but it wants it.. through us, because we want it. The fact our desire may turn out self-destructive is a separate thing. It's like drugs. Like this Marylin Manson's song "I don't want the drugs, but the drugs want me."
