I do think that is a real risk, yes. I don't want to use LLMs as a crutch to guard against having to ever learn anything new, or having to implement something myself. There is such a thing as productive struggle which is a core part of learning.

That said, I think everyone can relate to wasting an awful lot of time on things that are not "interesting" from the perspective of the project you are working on. For example, I can't count the number of hours I've spent trying to get something specific to work in webpack, and there is no payoff because today the fashionable tool is vite and tomorrow it'll be something else. I still want to know my code inside and out, but writing a deploy script for it should not be something I need to spend time on. If I had a junior dev working for me for pennies a day, I would absolutely delegate that stuff to them.
