What is the competitive advantage of authors in the age of LLMs?

Some one has to gain the original knowledge to build the original content and form cohesive arguments which can then be sucked up and hallucinated by LLMs to convey to the masses in some sort of incohesive fashion. Can an LLM create a 7 minute read article from only a few nebulous thoughts? Will it take as much time to coach an LLM into something to be read as it would taken to write the original article unaided?
