What does not get used, atrophies.

Critical thinking, forming ideas, writing, etc, those are too stuff that can atrophy if not used.

For example, a lot of people can't locate themselves without a GPS today.

To be frank I see it really similar to our muscles: don't want to lose it? Use it. Whether that is learning a language, playing an instrument or the task llms perform.
