I'll agree with that, especially if you're younger / less experienced and don't have a lot of code you've written banked from which you can pull. Cleaning up, or at least heavily reviewing, the vibe code for production may be a good way to hone your skills. The environment is kind of like that already with the existence of sites like Stack Overflow -- none of which were around when I was in university and getting started.
Way back then, the system administrator (4.3BSD on VAX-11/785 and, later, also earlier Sun systems) was also a very knowledgeable programmer and would answer SA/coding questions - eventually. His first answer was always, "Did you read the man page?" [Off to read man pages.] His second was, "Did you read the source code?" [Off to read BSD source.] Then he would lean back, with the keyboard still on his lap, and scribble something helpful on the whiteboard... It actually was a good, if annoying, learning process as I read a LOT of man pages and BSD source -- which helped me a immensely when I became a SA and systems programmer.
