This seems to assume that a skill is only important if you need it for your job.

If that is the case, then wouldn't this whole thing be a non-issue? We lose all the skills we used to have, but we don't need them because our entire job now is interacting with AI, and that skill we will continue to develop because it is what we do all day.

I don't know if I fully agree with that. Some skills are important even if you don't need them for your day job.
