I'm assuming your gotcha is going to be "but that's not vibe-coding", but in case you're sincere, you might not have realised this yet: there's a whole range between writing every line by yourself and letting the slop machine create the entire thing. You can rely on your knowledge and understanding to guide it, to the point that it writes code that you would have written, but saves you an enormous amount of time and effort looking up things and creating/running small tests to figure out details. It's a tool, not a spell, so your pearl clutching is a few years out of date...
