My personal take on fears about LLM is that they reduce the cost of producing things to the point that attribution is becoming pointless.

Attribution is a key social element for doing things. Being respected, recognised, honoured. If any intellectual product can be repurposed and stripped of its origin, there is little hope of that external validation.

Instead of that capitalistic view of intellectual produce, a few feudal lords are accumulating and exploiting it. In this environment the external validation is a serfdom expression.
