Total non-sequitur - it's entirely possible to be highly productive and also moderate your written language for a wider audience. What a ridiculous distinction to make.

In a world where code is written more and more by LLMs, these random human generated comments might hold anthropological value in some future.

Think of it akin to us studying cave paintings, wondering what whoever left their handprint on the cave wall was thinking when they did it. So these ancient lines of code might be studied in some future by our descendants, or whatever form we'll take. Interesting to perceive the author's frustration with said bit of code.

By comparison LLM generated code is neat and tidy with clean and clear comments. Plenty of that to go around for the future. No need to suck the soul out of every bit of code we currently have.
