I work with outsourced code all the time and it is a tyre fire without exception. I just spent a week scrubbing a codebase where some dev “did the needful” and committed an on-by-default flag to bypass authentication checks because he didn’t known how to set up his local work environment.

People report the same “took a shortcut” issue with AI vibe coding, and I can confirm that I’ve had to rewrite practically everything the AI generated for me, despite using a frontier model dialed up to 11 thinking levels.

Having said that, AI is very useful for other activities like PR review, security vulnerability analysis, typo hunting, reverse engineering, etc.

I’m probably going to have to increase my subscription to the next tier but at the same time I still can’t use any of the code it generates.

If even one person can simultaneously experience "very useful, need to pay more for it" and "useless output code quality" then of course you'd expect a variety of opinions amongst the general user base.
