The author of this post seems to have left something out. He never clearly states his thesis.

From what I can piece together he seems to think that agentic coded projects are being routinely dismissed as mere slop, and he feels that is wrong. But I’m not sure how that connects with the argument that if vibe coding were so great why haven’t we seen a duplicate of photoshop?

I can argue that vibe coding is bad even if someone produces something with it that seems good. Not saying I necessarily want to, but I could. Just because you have “90 test cases” that pass, or that you personally are happy with your own product is not proof of the success of vibe coding. (It is evidence, perhaps, but not proof… The evidence can be debated.)
