Any sort of atrophy of anything is because you don't need the skill any more. If you need the skill, it won't atrophy. It doesn't matter if it's LLMs or calculators or what, atrophy is always a non-issue, provided the technology won't go away (you don't want to have forgotten how to forage for food if civilization collapses).
Right. But (1) no longer needing the skill of thinking seems not obviously a good thing, and (2) in scenarios where in fact there is no need for humans to think any more I would be seriously worried about doomy outcomes.
(Maybe no longer needing the skill of thinking would be fine! Maybe what happens then is that people who like thinking can go on thinking, and people who don't like thinking and were already pretty bad at it outsource their thinking to AI systems that do it better, and everything's OK. But don't you think it sounds like the sort of transformation where if someone described it and said "... what could possibly go wrong?" you would interpret that as sarcasm? It doesn't seem like the sort of future where we could confidently expect that it would all be fine.)
