I often think back to the early GPT days before agents as maybe the last time I will deeply learn a technical subject. I think that was when I actually learned the most as I had to stay completely in the loop. I had recently started a new job and had to work with k8s for the first time. Using GPT to help me implement new services and help me diagnose and fix issues with kubectl taught me so much.

Now with agents I don't have any insights into what its doing with kubectl and would have no reason to learn how it works (other than my own curiosity).

I agree that the human no longer gains expertise, but I am not sure that will matter in the long run.
