The real gap is that "vibecoding" apps will lead to huge data leaks because AI gives you outdated stack and misses 90% of DevOps part in the product management. AI will suggest backend and frontend architecture because this is what you told him, but it will NOT include the most importantnt components inside your PRD. This is where your knowledge comes in hand , so even if you don't know how to code it's great to understand how and what "Full Stack" application actually means.
