And what will you do when that zero shot doesn't work, and continues not to work? It will always be necessary to dig in and manually change things, hence an editor or IDE will continue to be needed.
Yes this happens. Then I use "dumb" IDE like Goland... or, I didn't stop using it. My point is that I currently do not invest my time into learning "agentic IDE" like Cursor, since I am not sure this is something useful in the future.
