If writing is thinking then what happens if AI is doing the writing and reading?

I'm currently using a LLM to rewrite a fitness book. It takes ~20 pages of rambling text by a professional coach // amateur writer and turns it into a crisp clear 4 pages of latex with informative diagrams, flow charts, color-coding, tables, etc. I sent it out to friends and they all love the new style. Even the ones who hate the gym.

My experience is LLMs can write very very well; we just have to care.

Hubert Humphrey (VP US) was asked how long it would take him to prepare a 15 minute talk: "one week". Asked how long to prepare a two hour talk? "I am ready right now".

My experience is that people who think this are really bad writers. That's fine, because most human writing is bad too. So if your goal is just to put more bad writing into the world for commercial reasons, then there's some utility in it for sure.
