Some people like it better when they direct the solution because they walk away with a better understanding of it.

This has emotional/psychological aspects (it feels less like LLMs are replacing you), as well as practical ones (overall complexity is bounded by what the dev brain can understand/grasp).

A dev work becomes more and more about reliability, signing off safe software with a litmus test: “I will be on to handle this code failure as if I had written it”.

All the above points towards keeping tight control over some level of abstractions and delegating others.
