Yeah, that's a fair comment. I took "learned" to mean more than maybe the OP meant it to be. I stand by my broader point though - most people will use GPT without using it to expand their knowledge.
Only if it works flawlessly. If it has subtle bugs you spend about as much time solving the task with GPT as if you didn't use GPT. And it requires deep insight into what might go wrong.
Not necessarily, akin to using some other resource like stack overflow, I now know what the command was attempting to achieve and can debug it from there. ChatGPT is actually fantastic for breaking down outputs and explaining what it was trying to do at each part, which can help significantly for getting you to the final result you want
