Is it possible that the effectiveness of an LLM user with respect to the expertise of the user is like a sigmoid function or at least a step function in that shape? That is, one has to know something like the basic concepts and the vocabulary to bootstrap a programming project, but one does not have to know too much to do lots of meaningful work, and then again one needs to be en expert to build something extraordinary. Since most of the work is somewhere middle, most of us mere mortals are still concerned or stressed out for the possibility that LLMs will squeeze out too many job opportunities.
