From what I’ve seen so far, I would also not dismiss it as slop, even though I’m generally against vibe-coding (but more for ethical and environmental reasons, not because the code is inherently bad/slop/whatever). Many people seem to have a hard time acknowledging that LLMs actually can produce good stuff, but it highly depends on the experience of the developer who guides them.
If a dev is competent and has enough experience actually writing code and making good design decisions, I see no reason to judge their work on the basis of what tools they used to get the job done. However, it may still put me off, since I find it hard to value LLM-written code the same way I value human-written code, even though it may be equally good or even better in quality.
