Yeah, I similarly have not had great success for creating entire systems / applications for exactly this reason. I have had no success at all in not needing to go in and understand what it wrote, and when I do that, I find it largely needs to be rewritten. But I have a lot more success when I'm integrating it into the work I'm doing.

I do know people who seem to be having more success with the "vibecoding" workflow on the front end though.
