The way I see it, many of the "good" uses of LLMs boil down to easily counterfeiting traditionally-trusted indicators of human expertise, time investment, or intelligence.

For example: "Hey LLM, generate a smart sounding cover letter for a job at AcmeCo as a sales representative, highlighting my diligent work ethic and ability to generate new sales."

When the counterfeiting becomes widespread, those writing indicators become debased as receivers start to realize how easy they are to fake.

I wouldn't be entirely surprised if some of those prose-heavy documents started to move (culturally) toward raw bullet points.
