This is it for me. I can put up with a lot of struggle and non-sense if I feel like I'm actually developing some knowledge or skill. Vibe coding is a lot of the non-sense but little of the system knowledge actually sticks. Unless you very diligently try to understand every line, you're just as oblivious about the problem as you were when you started. At that point though the AI isn't making you any faster.

you didn’t learn much.

And that's entirely your fault, not the LLM's.
