Vibe coding is fine. Its just the next step.

Python for example is vibe coding compared to C. You pip install some library and just use it. Wanna modify a class instance variable and not use the proper accessor function? Sure, go right ahead.

The big thing about vibe coding is, as ironic as it sounds, prompt engineering. You can have tons of slop, but if it works, it works. The key defining factor is what constitutes as working. Namely, defining input output contracts, and automatic checks.
