As you say, if the subject is worth being written about, there should be no issue and writing will come naturally. If it’s a struggle, maybe one should step back and figure out why that is.
There may some argument for speed, because writing quality prose does take time, but then the question becomes a matter of quantity vs. quality. Do you want to write high quality pieces that people want to read at a slower pace or churn out endless volumes of low-substance grey goo “content”?
Like, you can write a bunch of text, then ask an LLM to improve it with minimal changes. Then, you read through its output and pick out the improvements you like.
I'm personally not as gloomy about it as the parent comments but I fear it's a trend that pushes towards a samey, mass-produced style in all writing.
Eventually there will be a counter culture and backlash to it and then equilibrium in quality content but it's probably here to stay for anything where cost is a major factor.
