I think it's for the individual to choose when and when not to use AI, and that can help them stay up-to-date and using their noggin. Then beyond that I think they need to make a concise effort to stay up-to-date, whether their job gives them that opportunity or they do it outside of work at home.
AI isn't new to this issue, when we were hiring we had a lot of trouble because people lose the desire to learn, the longer they work. I couldn't tell you how many SDEs we interviewed that used 10 year old versions of php/c#/jquery/etc, and had no intentions of learning modern tech.
