We know that learning and building mental capabilities require effort over time. We know that when people have not been applying/practicing programming for years, their skills have atrophied. I think a good default expectation is that unused skills will go away over time. Of course the questions are, is the engagement we have with LLMs enough to sustain the majority of the skills? Or is there new skills one builds that can compensate foe those lost (even when the LLM is no longer used)? How quickly do the changes happen? Are there wider effects, positive and/or negative?
