I always tend to think in terms of technology whether it's enhancing or diminishing the potential of the user. A bow is more powerful than a stick but also develops more motor skills, a bike develops the users body more than a car, and so on. Another way to put is is ask yourself whether adopting a given piece of technology is likely to turn you into the Wall-E people[1] or the opposite.
The article is basically an ad for some LLM product and sounds like it's written by one. I don't think the way people use them develops their mental faculties. If you want to organize your thoughts just use a system like Zettelkasten because you have to put conscious thought into your organizing, and if you want to learn to write don't take cues from a chatbot.
