Today's high-end LLMs can do a lot of unsupervised work. Debug iterations are at least junior level. Audio and visual output verification is still very week (i.e. to verify web page layout and component reactivity). Once the visual model is good enough to look at the screen pixels and understand, it will instantly replace junior devs. Currently if you have only text output all new LLMs can iterate flawlessly and solve problems on it. New backend dev from scratch is completely doable with vibe coding now, with some exceptions around race conditions and legacy code comprehension.

Curious if you gave Antigravity a try yet? It auto-launches a browser and you can watch it move the mouse and click around. It's able to review what it sees and iterate or report success according to your specs. It takes screen recordings and saves them as an artifact for you to verify.
I only tried some simple things with it so far but it worked well.
