If you don't understand what the copy/paste is actually doing, you shouldn't be script-kiddying it in your project. If you do understand, then the AI is just quickly writing what you already intended.
If you are having to understand something you didn't understand, it's probably taking a bunch of time to read and verify what the script does. This can be a good learning experience and reveal unknown unknowns, but probably isn't a massive speedup.
This seems false to me. I vibe code shell scripts all the time. I understand what it's doing perfectly, but it would have taken me ages to look up all the bash syntax and get it all correct. Is it one square bracket pair around if statements, or two?
You are in the category I mentioned that already know the answer and are using AI to write the code you already understand faster. This is rather different from “vibe coding” in my opinion.
