Even medium human writers can comprehend their work as a whole, though. There is a cohesiveness even to the bullshit. The LLM is just putting words down that match the prompt. It’s rng driven, readable Lorum Ipsum.
If the results were still edited afterwards, there may be some merit to the output, but any company going full LLM isn’t looking for quality. They want to use it to churn out endless content that they simply can’t get from even a team of humans. More than could be edited even if they kept editors on staff.
