I honestly don't feel there is much atrophy or this is an issue at all
As if for example someone's skill lessened if they switched from assembly to a higher level programming language over time (like, does it matter?)
If you for some reason had to go back and program more manually, then you could do so as the need arises
Otherwise, LLMs appear to be here to stay and you don't actually need those skills that are even possibly admittedly "atrophying"
I guess we'd need a detailed pinpointing of what skills exist or existed and to identify if they actually ateophy (I guess I'm not sure if skills are really atrophying, or even if they are if it matters)
Edit: here's an idea or exercise or projects to work on. Maybe people should find clear documentation of pre-AI processes in case you need to go back and learn them. Or create such documentation if it doesn't exist (which would be an exercise to practice your skills to make you remember them).
