I have seen a decent amount of software developed via vibe coding, i.e., coding with heavy AI assistance but I have not seen anything that is passable as professionally-developed software. One big tell is that the AI assistant tends to add in copious boundary condition checks that’d never occur to humans because they are unlikely to occur in practice. Another is bizarre style, which imposes a heavy cognitive cost on the reader (whose time is qualitatively more valuable than that of the computer).
For people who basically can’t code anywhere near a professional level, I see why this is valuable, but I think these people should be honest with themselves and admit they can’t really code, and wouldn’t know good code if it hit them in the face.
For people who can (and who can already avail themselves of various autocompletion tools whether AI-powered or knowledge-based), I don’t see the value proposition. It creates hard-to-review code and code review is a more difficult, important, cognitively taxing, and rarified skill than development itself, so this technology could, in the worst case, actually drive up the already high cost of software development.
